Estudo da corrosão em ligas de alumínio utilizadas na indústria aeronáutica

A resistência e o mecanismo de corrosão das ligas de alumínio 2024, 7010, 7050 e 7475 foram estudados em solução de NaCl. Os efeitos do tratamento térmico nas ligas, concentração de oxigênio, pH, adição de oxi-ânions e temperatura do meio constituem algumas das variáveis estudadas. Primeiramente, procedeu-se à caracterização físicoquímica dos materiais através de análise química e metalográfica, mediante microscopia eletrônica de varredura e espectroscopia de energia dispersiva. As ligas 2024, 7010, 7050 e 7475 como recebidas, recozidas e envelhecidas, revelaram a existência de partículas ternárias e quaternárias, constituídas por Al:Cu:Fe e Mg ou Zn. Também foi observado um maior número de partículas pequenas de composição variável situando-se, preferencialmente, nos contornos dos grãos. Os resultados dos ensaios de corrosão em meios aerados e desaerados indicam que o cromato é efetivo como inibidor da corrosão localizada em ambas ligas e que o molibdato somente na liga 7050. O efeito inibidor do tungstato se revela em meio desaerado e é comparativamente menor daquele observado com os outros oxi-ânions. As análises quantitativas de superfície das ligas após os ensaios de imersão indicam que ainda na presença de inibidor, se pites foram nucleados, eles crescem.

Avaliação econômica de diferentes composições veiculares empregadas no transporte rodoviário de madeira: estudo de caso

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

Estudo da viabilidade técnica, econômica e ambiental da substituição de um banco de resistências elétricas de aquecedores por uma caldeira alimentada por biomassa de paletes residuais na indústria de laminação

Given the increasing demand for fossil fuels to power the engines of the global economy, and also the slow process of synthesis of oil, it becomes necessary to develop new sources of renewable energy in addition to improve promising sources that already exist, turning them competitive. Based on this, biomass is shown very promising between the most popular energy sources due to its availability, applicability, and above all, the fact of not emitting green house gases when analyzing the whole carbon cycle. In this sense, this work presents, through an environmental, technical and economic analysis, the impact in an aluminum mill of replacing the use of electricity, in one process, by a boiler fueled with biomass from waste process of packaging the finished product with pallets. Thus, besides the reduction of CO2 emissions, financial gains are targeted, since the main goal of the corporations that require such power is to maximize its profits

Criação e implantação de procedimentos logísticos em uma indústria de móveis: estudo de caso

The Brazilian construction is with high production which resulted in many service industries and also for businesses that work in conjunction with it. For the furniture industries would not be different, since they are intimately involved with the construction. To meet the demand for furnishings in Brazil, some clusters of industries have developed in recent years, as in the case of Uba (MG), Arapongas (PR) and Bento Gonçalves (RS). For industries sector can always increase its production combining quality and customer satisfaction, is necessary for their production procedures are studied and improved every day. The aim of this research is to propose a solution for simple information system involving the issue of tracking parts of the furniture produced in an industry custom furniture that depend on outsourced services. The research occurred during four months of the year 2013 for the observation of the production of the industry, where possible observing interference could be carried out with the aim of obtaining improvements in the production line. It is concluded that control of the finished product in a custom furniture industry is a very complex work, because the information system must transmit information faithful, which has not happened formerly, but after the implementation of the identification system was significant improvement the transfer of information between sectors mounts internal and external furniture

Otimização do processo de MRP (Material Requirement Planning) de embalagens: uma aplicação da metodologia lean six sigma em uma indústria de agronegócios

There is a growing search for continuous improvement within the companies which creates an obligation of reducing and when it is possible eliminating waste. Production Planning and Control Department (PCP) is not out of this question, making necessary the application of methods and creation of tools that eliminate steps which do not add value to the planning process. This paper aims to develop a tool which concentrates in just one place all the necessary information to make the packaging material requirement planning (MRP) in a agribusiness company. Besides, it also aims, in a more visual way and using devices that prevent mistakes (Poka-Yoke), to reduce the number of reviews and mistakes made by analysts. As a result, an Excel spreadsheet was developed. This spreadsheet shows what happens with the status of planning and receiving of packaging, giving some advices when some critical situation happens. The use of Lean Manufacturing Method and the action research method helped to well define the problem and to reduce the number of steps, spreadsheets and time of process in 80%, 60% and 75%, respectively
