Performance de gênero no feminino e no plural: travestilidade, violência e abjeção

This research investigates on gender performance in trans women, through bibliographical research, with the aim of building the script: family home scenic. We analyze essential concepts of gender studies to discuss the experience of these subjects, a brief history of motion picture LGBTT, data on violence suffered by this group, in official reports and hemerográficos, noting the fragility of the data and the high degree of imprecision. Also we discuss about the feminine, a gender role that socially generates vulnerabilities, as can be seen in cisgêneras women, Transgender and gay men effeminate. The bibliographical research served the theatrical script homestay, churning out a product accessible to the community.

Oficina educomunicativa de produção de vídeos: construção de significados sobre problemas socioambientais

This research aims to analyze the meaning making by Elementary Education students from public schools of Uberlândia (Minas Gerais, Brazil) about the social and environmental problems of their surroundings as of audiovisual reading and expression skills. The theoretical framework is based on constructivism, through the study of contributions about: cognitive development; meaningful learning; cognitive processes and types of knowledge; principles of learning with technology; educommunication focused on critical media literacy; and critical environmental education. The study object is a video production workshop organized in nine meetings, from September to November 2015, attended by 15 students. The following data collection instruments were used: the materials produced by the participants, specifically guided critical media literacy, agenda, script and final video; researcher observations from his role as a mediator; and focal interviews. The analysis was divided into two axes: procedural knowledge – technical skills of critical media literacy and production; and conceptual and metacognitive knowledge – representation of social and environmental problems and metacognitive skills of critical media literacy. Data were coded in the form of a skill evaluation rubric and also in the form of graphs. Thus, despite the time constraints, it is inferred that the workshop helped students to deepen their understanding about the discussed content, which is reinforced by observing in the graphs how the constant progressive differentiation of more inclusive concepts occurred along the meetings. It is further considered that the workshop contributed to the students reflect on their way of learning through critical use of techniques of media literacy and production, which can be seen from the satisfactory learners performance in most elements evaluated by the rubrics, as well as from the success in identifying interlocutors, values and actions in the read and built texts, something revealed by the graphs.

Comunicação pública e acesso à informação: o interesse público presente nas produções da assessoria de imprensa da prefeitura de Santarém (PA)

Public communication is based on the public interest and the effective democratization of communication in publics agencies. Access to information is the base for this is materializes solidly, helping even in formation as an individual. The work of the press office is the instrument for the Public Communication and access to information is guaranteed to society , since one of the goals of the press officer is to be committed to media , providing it material quality and depth , benefiting so the citizen. The research the look exactly on reflections on the topics listed above. The purpose of this study was to analyze the news published in Fanpage and Santarem Town Hall site, in western Para, meet the demands of Public Communication and the precepts of the Access to Information Law (AIL), starting the questioning until point to Santarem Town Hall works to public communication. For this analysis, we developed a work using the techniques of bibliographic and descriptive research. Such referrals have served as a starting point for fieldwork and for exhibition on the concepts of Public Communication of Access to Information Law, Organizational Communication and Press office. The research was considered, also, because document was to identify and verify the documents with a specific purpose. This research was lifting a quantitative survey to support the qualitative analysis of the object. So considering its features is that it was monitor the Fanpage and the Town Hall site, through a specific tool and then the analysis of posts, searching to observe public communication accomplished in the Town Hall of Santarem, on the Internet, especially social media and corporate website. The methodology helped obtain indicators that allowed add knowledge about the production of the Town Hall press office, and identify if the press office productions meet AIL and Public Communication. Finally, it was suggested in this study the elaboration a strategic script of communication because it scales the actions and policies of the Santarem city, allowing citizen participation. For this, too, it suggested the training of Santarem municipal government communication team as a strategy. This training consists of speeches and wheels conversations with all the press officer of the town hall, including the secretariats.

Intervenção mediacional e hábitos alimentares: um estudo de crianças com síndrome de Down

The inadequacy about eating habits have been established as a serious problem nowadays. It is a multifactorial and difficult to handle, given their different nuances and causes. A population particularly exposed to the bad eating habits arising harm are individuals with Down syndrome, both with regard to the aspects inherent to the individual's own condition, regarding eating misfits, making it the weight control a necessary measure for a proper development. Thus, this study aimed to develop and evaluate a proposal based nutrition education from the assumptions of mediated learning, with children three to four years with Down syndrome. The participants were five children, four girls and a boy. Also included his parents and / or guardians. The data collection procedure involved the use of eight playful workshops with children and nutritional evaluation of those five meetings with parents and three home visits with each participating family. We tried to build with these children and their families a nutritional education to contribute to their daily choices of eating. Using listening, observation and questionnaire, besides playful interventions, it was observed that the first meaning of the act of eating is built in the family and reinforced by their social life. Overall, our sample characteristics seem to agree with the literature. During the intervention, the children showed attention, but little understanding of the content. With mothers, the results were different, with reflections on the inadequate power both the type of food offered, and quantity and so this offer is performed, conducted along the interventions changes in your lifestyle, such as perception of influence they had on their children in the formation of their eating habits, as well as less frequent intake of soft drinks and sweets. Nutritional interventions and mediations conducted with the mothers is that they seem to be effective strategies to combat obesity. Face of what was discussed, we see the importance of implementing intervention measures in combating and preventing overweight or obese since childhood, particularly with children with Down syndrome. One should prevent childhood obesity with educational and informative measures from birth, with family and with each child, through the primary health care and schools.

Serious Game no tratamento de obesidade infantil: uma proposta de interação natural com monitoramento remoto

The number of overweight people has increased in the last few years. Factors such as attention to diet and changes in lifestyle are crucial in the prevention and control of obesity and diseases related to it. Experts believe that such actions are most effective when initiated during childhood, and that children raised in an environment that encourages physical activity ultimately become healthier adults. However, to arouse and maintain interest in such activities represent a major challenge, which are initially perceived as repetitive and boring, and, thus, soon abandoned. Computer games, traditionally seen as stimulants to a sedentary lifestyle are changing this perception using non-conventional controls that require constant movement of the player. Applications that combine the playfulness of such games to physical activity through devices, like Microsoft Kinect, might become interesting tools in this scenario, by using the familiarity of Natural User Interfaces along with the challenge and the fun of video games, in order to make attractive exercise routines for schoolchildren. The project carried out consists of an exergame composed of several activities designed and implemented with the participation of a Physical Educator, aimed at children between eight and ten years old, whose performance and progress can be remotely monitored by a professional via web interface. The application arising from this work was accompanied by tests with a group of graduating Physical Education students from the University of Rio Verde GO, and subsequently validated through questionnaires whose results are shown on this work.

Interações magnéticas e elétricas em GaMnAs

In this paper, we will address together the magnetic and electrical properties of a particular semiconductor, the GaMnAs. The treatment will be done analytically in the first part of the work, according to the computational method for simulation of physical systems through the implementation of the expressions obtained in the first part. All study of magnetic contribution will be made using an interaction Kondo type, using an approach by Green functions. The electrical part, which consists of the Coulomb interactions between carriers and Mn ions, will be treated within the approach of multiple scattering. The implementation of the proposed method will calculate the Green functions converged as multiple scattering solution and use them as a starting point for the calculation of the effective magnetic interactions between Mn ions mediated charge carriers. The concentration parameters were varied for Mn ions and carriers as well. The combination of these two parameters can lead to insulating, metal samples with carriers in Fermi level to low or high mobility. As a result a correlation between the obtained carrier mobility and the strength of magnetic interaction. The greater mobility, the greater the intensity of the interaction.

Ensino colaborativo e educação física: contribuições à inclusão escolar

In Brazil, special education public is a challenge to all teachers, especially to Physical Education ones. Among others, it encompasses students with disabilities, students with intellectual giftedness, and students with pervasive developmental disorder. Besides posing challenges, the inclusion process causes worry and generates debates on problems that impede the full partaking of such pupils in schooling practices related to physical education. This thesis presents a research that focused on these matters by means of co-working involving the researcher and the Physical Education teacher in regular classrooms following co-teaching perspective. The starting point of the research is the following question: what contributions co-working involving Physical Education teacher and researcher may provide to people with disabilities and to Physical Education teacher in regular schools attended by students who are the special education’s target? The research aimed at discussing and analyzing the development of such co-working activity involving the researcher and Physical Education teacher. It followed co-teaching perspective and was put into practice in a public school in Uberlândia, state of Minas Gerais. Participant qualitative approach, which recognizes relations between social sciences and intervention in social reality, was the methodological choice to develop the research in three phases: 1) making the research; 2) intervening in social reality; 3) assessing/diagnosing it. Strategies to gather data included semi structured interview, questionnaire, participant observation, and group interview. Data come, above all, from oral accounts as well as from the work by the group of participants of the research, which means, researcher, Physical Education teacher who works at regular schools and three teachers who deal with AEE (Atendimento Educacional Especial), a special educational teaching program. The concept of inclusion is discussed accordingly to authors such as Miranda (2001), Mantoan (2001), Duarte and Santos (2003), Mittler (2003), Rodrigues (2006), and Bueno (2008). The conception of co-working is developed in the light of studies by Capellini (2004) and Mendes (2009), among others. Results point out not only initial conditions of anguish, doubts and hardships, but also a will to debate difficulties Physical Education teachers face in their daily pedagogical activities at school. Likewise, results showed that teachers who took part in the research are interested in continuing their training in connection with co-teaching as strategy to teach physical education at inclusive schools.

Entre as tramas da indústria da moda: argumentos sobre o trabalho escravo contemporâneo na sociedade de consumo

Even after its abolition, the slave labor still exists in the world. In a new socio-historic context, the shackles and slave quarters have been left behind, nowadays the workers are tempted, subjected to degrading conditions and have their rights retrenched. The contemporary slave labor has been emerging as subject of research in the Organizational Studies since the early 2000s, calling attention to many gaps to be filled about the way organizations all around the world use this practice. Contemporary slave labor is found in many and various economic activities, since coal to textile industries or even stores. In this dissertation, we have incorporated the consumption dimension to the field of Organizational Studies, discussing the modern slavery, aiming to understand the consumers’ point of view about this topic, that is, we have researched the consumers’ interpretations concerning the slave labor in the fashion industry. Our objective is to analyze consumer’s argumentative construction in the decision of buying or not products made by industries from the fashion field that were denounced because of slave labor usage. We have adopted fashion industry as research focus because it obscures the reflection of the consumers that feel like in a new world while shopping, a world of beauty and fantasy, seeking their own satisfaction. Furthermore, the Brazilian fashion industry is one of the biggest of the world (ABIT, 2015), with a huge symbolic strength in the country. We have realized a qualitative research using semi-structured interviews with 35 consumers to identify their arguments according to the criteria defined by Liakopoulos (2002): data, propositions, guarantees, supports and refutations. The data are the statements used by the interviewees categorically, that is, those which are clear in the interviews. The propositions are what qualifies and justifies the used data. The guarantees are related to the nature of the data, they are what gives the sense to the data and are introduced implicitly in the interviewee speech. The supports are universal premises introduced in order to legitimate the arguments. The refutations, when present, counter the used arguments. As results, we’ve found consumers who developed arguments pro-consumption and anti-consumption and who have defended ideas about the responsibility of different actors for the existence of this practice and for the fight against it. From these two categories: (1) pro-consumption – consume despite the complaints and (2) anti-consumption – don’t consume, because of the accusations; we have identified the following argumentative lines: skepticism, faultfinding and moral engagement. By the end, we have presented the interviewees’ argumentative construction and the obtained results.

Impacto na epidemiologia da sepse tardia após a mudança do protocolo de antimicrobianos em uma UTIN de um serviço universitário

Advances in neonatology resulted in reducing the mortality rate and the consequent increase in survival of newborn pre terms (PTN). On the other hand, there was also a considerable increase in the risk of developing health care-related infection (HAI) in its most invasive, especially for bloodstream. This situation is worrying, and prevent the occurrence of it is a challenge and becomes one of the priorities in the Neonatal Intensive Care Unit (NICU). Sepsis is the main cause of death in critical neonates and affects more than one million newborns each year, representing 40% of all deaths in neonates. The incidence of late sepsis can reach 50% in NICUs. Currently the major responsible for the occurrence of sepsis in developed countries is the coagulase negative Staphylococcus (CoNS), followed by S. aureus. The cases of HAIs caused by resistant isolates for major classes of antimicrobial agents have been increasingly frequent in the NICU. Therefore, vancomycin has to be prescribed more frequently, and, today, the first option in the treatment of bloodstream infections by resistant Staphylococcus. The objectives of this study were to assess the impact on late sepsis in epidemiology III NICU after the change of the use of antimicrobials protocol; check the frequency of multiresistant microorganisms; assess the number of neonates who came to death. This study was conducted in NICU Level III HC-UFU. three study groups were formed based on the use of the proposed late sepsis treatment protocol, with 216 belonging to the period A, 207 B and 209 to the C. The work was divided into three stages: Period A: data collected from neonates admitted to the unit between September 2010 to August 2011. was using treatment of late sepsis: with oxacillin and gentamicin, oxacillin and amikacin, oxacillin and cefotaxime. Period B: data were collected from March 2012 to February 2013. Data collection was started six months after protocol change. Due to the higher prevalence of CoNS, the initial protocol was changed to vancomycin and cefotaxime. Period C: data were collected from newborns inteerne in the unit from September 2013 to August 2014. Data collection was started six months after the protocol change, which occurred in March 2013. From the 632 neonates included in this study, 511 (80,8%) came from the gynecology and obstetrics department of the HC-UFU. The mean gestational age was 33 weeks and the prevailing sex was male (55,7%). Seventy-nine percent of the studied neonates were hospitalized at the NICU HC-UFU III because of complications related to the respiratory system. Suspicion of sepsis took to hospitalization in the unit of 1,9% of newborns. In general, the infection rate was 34,5%, and the most frequent infectious sepsis syndrome 81,2%. There was a tendency to reduce the number of neonates who died between periods A 11 and C (p = 0,053). From the 176 cases of late sepsis, 73 were clinical sepsis and 103 had laboratory confirmation, with greater representation of Gram positive bacteria, which corresponded to 67.2% of the isolates and CoNS the most frequent micro-organism (91,5%). There was a statistically significant difference in the reduction of isolation of Gram positive microorganisms between periods A and C (p = 0,0365) as well as in reducing multidrug-resistant CoNS (A and B period p = 0,0462 and A and C period, p = 0,158). This study concluded that: the CoNS was the main microorganism responsible for the occurrence of late sepsis in neonates in the NICU of HC-UFU; the main risk factors for the occurrence of late sepsis were: birth weight <1500 g, use of PICC and CUV, need for mechanical ventilation and parenteral nutrition, SNAPPE> 24 and length of stay more than seven days; the new empirical treatment protocol late sepsis, based on the use of vancomycin associated cefepime, it was effective, since promoted a reduction in insulation CoNS blood cultures between the pre and post implementation of the Protocol (A and C, respectively); just as there was a reduction in the number of newborns who evolved to death between periods A and C.

Cidades saudáveis e qualidade de vida em Uberlândia (MG): aportes metodológicos para um processo em construção

The current study includes theoretical and methodological reflections on the quality of life in the city of Uberlândia, Minas Gerais. It started from the thought that the quality of life is multifactorial and is permanently under construction and the main objective of analyzing it as one of the componets of Healthy Cities's moviment. The theoretical research focused on the concepts of healthy cities, quality of life, health, sustainability, well-being, happiness, indexes and indicators. From the use of multiple search strategies, documentary and on field of quantitative and qualitative character, this research of exploratory descriptive nature can offers a contribution to the studies on the quality of life in cities. It is proposed that the studies startes to work with some concept, like some notions os life quality adequated for some paticular reality, whose notions can approach concepts already established as health. This step is important on the exploratory researches. The studies may include aspects of objective analysis, subjective or both. The objective dimension, which is most common approach, are traditionally considered variables and indicators related to: the urban infrastructure (health, education, leisure, security, mobility), dwelling (quantitative and qualitative dwlling deficit), the urban structure (density and mix uses), socioeconomic characteristics (age, income, education), urban infrastructure (sanitation, communication), governance (social mobilization and participation). To focus on the subjective dimension, most recent and unusual, it is proposed to consider the (dis)satisfaction, the personal assessment in relation to the objective aspects. In conclusion, being intrinsically related to the health, the quality of life also has a number of determinants, and the ideal of the reach of quality of life depends on the action of all citizens based on the recognition of networks and territories, in a interescalar perspective and intersectoral. Therefore, emphasis in given on the potential of tools, such as the observatories, to monitor and intervent in reality, aiming in a building process of healthy cities.

Configurações para métodos de acesso por escaneamento

The use of access technologies for communication, based on scanning methods, enables new communication opportunities for individuals with severe motor dysfunction. One of the most commom examples of this type of technology is the single switch scanning. Single switch scanning keyboards are often used as augmentative and alternative communication devices for inidividuals with severe mobility restrictions and with compromised speech and writing. They consist of a matrix of keys and simulate the operation of a physical keyboard to write messages. One of the limitations of these systems is their low performance. Low communication rates and considerable errors ocurrence are some of the few problems that users of these devices suffers during daily use. The development and evaluation of new strategies in augmentative and alternative communication are essential to improve the communication opportunities of user who make use of such technology. Thus, this work explores different strategies to increase communication rate and reduce user’s mistakes. Computational and practical analysis were performed for the evaluation of proposed strategies.

Efeito da geometria do implante dentário e do protocolo de fresagem óssea na estabilidade primária e na osseointegração inicial: estudo experimental em cães

CHAPTER 1 - This study histologically evaluated two implant designs: a classic thread design versus another specifically designed for healing chamber formation placed with two drilling protocols. Forty dental implants (4.1 mm diameter) with two different macrogeometries were inserted in the tibia of 10 Beagle dogs, and maximum insertion torque was recorded. Drilling techniques were: until 3.75 mm (regular-group); and until 4.0 mm diameter (overdrillinggroup) for both implant designs. At 2 and 4 weeks, samples were retrieved and processed for histomorphometric analysis. For torque and BIC (bone-to-implant contact) and BAFO (bone area fraction occupied), a general-linear model was employed including instrumentation technique and time in vivo as independent. The insertion torque recorded for each implant design and drilling group significantly decreased as a function of increasing drilling diameter for both implant designs (p<0.001). No significant differences were detected between implant designs for each drilling technique (p>0.18). A significant increase in BIC was observed from 2 to 4 weeks for both implants placed with the overdrilling technique (p<0.03) only, but not for those placed in the 3.75 mm drilling sites (p>0.32). Despite the differences between implant designs and drilling technique an intramembranous-like healing mode with newly formed woven bone prevailed. CHAPTER 2 - The objective of this preliminary histologic study was to determine whether the alteration of drilling protocols (oversized, intermediate, undersized drilling) present different biologic responses at early healing periods of 2 weeks in vivo in a beagle dog model. Ten beagle dogs were acquired and subjected to surgeries in the tibia 2 weeks before euthanasia. During surgery, 3 implants, 4 mm in diameter by 10 mm in length, were placed in bone sites drilled to 3.5 mm, 3.75 mm, and 4.0 mm in final diameter. The insertion and removal torque was recorded for all samples. Statistical significance was set to 95% level of confidence and the number of dogs was considered as the statistical unit for all comparisons. For the torque and BIC and BAFO, a general linear model was employed including instrumentation technique and time in vivo as independent. Overall, the insertion torque increased as a function of drilling diameter from 4.0 mm, to 3.75 mm, to 3.5 mm, with a significant difference in torque levels between all groups (p<0.001). Statistical assessment of BIC and BAFO showed significantly higher values for the 3.75 mm (recommended) drilling group was observed relative to the other two groups (p<0.001). Different drilling dimensions resulted in variations in insertion torque values (primary stability) and different pattern of healing and interfacial remodeling was observed for the different groups. CHAPTER 3 - The present study evaluated the effect of different drilling dimensions (undersized, regular, and oversized) in the insertion and removal torques of dental implants in a beagle dog model. Six beagle dogs were acquired and subjected to bilateral surgeries in the radii 1 and 3 weeks before euthanasia. During surgery, 3 implants, 4 mm in diameter by 10 mm in length, were placed in bone sites drilled to 3.2 mm, 3.5 mm, and 3.8 mm in final diameter. The insertion and removal torque was recorded for all samples. Statistical analysis was performed by paired t tests for repeated measures and by t tests assuming unequal variances (all at the 95% level of significance). Overall, the insertion torque and removal torque levels obtained were inversely proportional to the drilling dimension, with a significant difference detected between the 3.2 mm and 3.5 mm relative to the 3.8 mm groups (P < 0.03). Although insertion torque–removal torque paired observations was statis- tically maintained for the 3.5 mm and 3.8 mm groups, a significant decrease in removal torque values relative to insertion torque levels was observed for the 3.2 mm group. A different pattern of healing and interfacial remodeling was observed for the different groups. Different drilling dimensions resulted in variations in insertion torque values (primary stability) and stability maintenance over the first weeks of bone healing.

A Fraternidade como categoria política: princípio anunciado na educação brasileira

This dissertation has had the goal of understanding and discussing how the fraternity category is presented in the main Brazilian education laws after the promulgation of the 1988 Federal Constitution. The systematization of a theoretical base about the fraternity category in its relation with de Brazilian education regulatory landmarks has allowed the proposition of elements of this category. The process of building the theoretical references of this research was written from a historical recuperation of the French Revolution, taking into account the triad of its main principles, “liberty, equality, and fraternity”, as civic and political values. Likewise, the Haitian Revolution was considered because of the symbolic role this revolution played on the concretization of the triad through the slave and black people’s struggle whose aims were both participation in the colony’s power positions and in the abolishing of slavery. The modernity and post modernity issues, as well as the concepts of citizenship and human rights, are also took as theoretical references in order to identify characteristics and connections of each one of those themes and concepts with the fraternity as a political category. This analysis has allowed the elaboration and systematization of the fraternity category and its constitutive elements: the universality which is directly connected to the local and regional issues; the mondialization as a counter-argument to the globalization which is seen exclusively in its economic dimension; the participative democracy as alternative way to the representative democracy; the “alteridade” (a kind of altruism) due to its specific way to recognize the other one as someone pretty much like me; and the diversity which consider the multicultural perspective and the necessity of building unity. It was possible to identify that the first two elements of the triad, liberty and equality, were the most import ones over the so called modernity period when the triad was put in the second place or only in its religious dimension. The post modernity, in turn, has brought to light the fraternity due to its constitutive elements. It was also possible to highlight the citizenship as a modernity landmark and the human rights as an idea marked by the fraternity and directly linked with the post modernity. From this theoretical frame it was made an analysis of the legal instruments that organize and regulate the Brazilian education: the 1998 Federal Constitution; the Statute for Children and Adolescents; the National Brazilian Education Law; and the National Education Plan. All these legal instruments were discussed based on their relation with the fraternity as a political category and through the identification of its main constitutive elements. The methodological way was put into practice mainly through the qualitative dimension, especially the Bardin’s content analysis. The dissertation has permitted to emphasize that the fraternity as political category was not a forgotten principle in the Brazilian education legislation, but a principle not formally and textually declared yet.

Influência da utilização do fluido de corte com adição de grafeno na temperatura de usinagem e formação de rebarba no processo de micro fresamento

As time passed, humanity needed the development of new materials used in various activities. High strength materials such as titanium and Inconel for example, had been studied because they are widely used for implants in biomedicine, as well as their use in aerospace and automotive industries. Because of its thermal and mechanical properties, these materials are considered difficult to machine, promoting a rapid wear of cutting tools, primarily caused by the high temperatures in machining. With the development of new materials has emerged the need of developing new manufacturing processes. One of today’s innovative processes is the micro-manufacturing. Being a process with a defined cutting tool geometry, burr formation is a constant and undesirable phenomenon formed during the machininig process. Being detrimental to the manufacturing process, overspending deburring operations are constantly employed leading to increase the aggregate cost to the manufactured material. Assembly components are also impaired if there is no control of the burr, with consequences including the disposal of components due to the occurence of this phenomenon. This paper presents the study of micro-milling Inconel 718, investigating influential parameters in the formation of burrs in order to minimize the occurrence of this phenome non. Different feed rates per tooth and cutting speed are evaluated, and different cutting fluids with different methods of applying the fluid. Adding graphene to cutting fluids was considered as a variable to be investigated, which is considered an excellent solid lubricant, in addition to increasing the thermal conductivity of the cooling solution (AZIMI; MOZAF FARI, 2015). The micro-milling temperature was evaluated in the present work. It was observed a new phenomenon that causes the machined surface temperature decreases below room temperature when using the solution water + oil. This phenomenon is explained in further chapters. In order to unravel this phenomenon, a new test was proposed and, from this test, it can be concluded, comparatively, which cutting fluid has a better cooling property.Using cutting fluid with different thermal properties has shown influence when analy zing burr formation and reducing machining temperature.

Avaliação tribológica de novas modificações superficiais para cilindros de laminação a frio

The present work analyzed the tribological behavior of coatings/surface modifications traditionally used in cold rolling mill rolls and new coatings/surface modificationswith potential to replace the carcinogenic hard chrome. The study started with identification of wear mechanisms occurring in real coldrollingmill rolls. Due the high cost and dimensions of the rolls, thereplication technique was used. Replicas were obtained from 4 different rolling millBrazilian companies before and after a normal rolling campaign. Initial sliding tests were conducted using spherical and cylindrical counter bodies in order to verifywhichtribological conditions allowed to reproduce the wear mechanisms found in the replicas. These tests indicated the use of reciprocating sliding tests with cylindrical counter bodies (line contact), normal load of 100 N, and test times of and 1 h and 5 h. Different surface modifications were carried out on samples produced from a fragment of a rolling mill roll. The specimens were heat treated and ground on both sides. After, some specimens were surface textured by electrical discharge texturing (EDT). For both groups (ground and EDT), subsequent treatments of chromium plating, electroless NiP coating and plasma nitriding were carried out. The results of the reciprocating tests showed that specimens with electroless NiP coating presented the lowest friction coefficients, while plasma nitrided specimens showed the highest. In general, previous surface texturing before the coating/surface modification increased the wear of the counter bodies. Oneexceptionwas for EDT with subsequent electroless NiP coating, which presented the lowest counter bodies wear rate. The samples withelectroless NiP coating promoted a tribolayer consisting of Nickel, Phosphorus and Oxygen on both the specimens andthecounter bodies, which was apparently responsible for the reduction of friction coefficient and wear rate. The increase of the test time reduced the wear rate of the samples, apparently due the stability of the tribolayers formed, except for the nitrided samples. For the textured specimens, NiP coating showed the best performance in maintaining the surface topography of the specimens after the sliding tests.
