Tribocorrosion response of the Ti6Al4V alloys commonly used in femoral stems

In prosthesis, tribochemical reactions occur at the stem/bone interface. When coupled with micromotions it can lead to the loosening of the implant, osteolysis, release of metal ion and wear particles. The effect of these movements and the underlying mechanisms are quite unknown. This work investigates the tribocorrosion behavior of etched Ti6Al4V alloys under reciprocating sliding. Tests were performed in a phosphate buffer solution (PBS) containing proteins. A normal load of 1 N and anodic potentials of -0.1 and +0.5 V/SCE were applied. The destruction pathways of the top surface layers (adsorbed proteins, passive film) were studied. The results showed that the favorable/undesired effect of proteins in solution depends on the characteristics of the passive film under a mechanical stress. (C) 2013 Elsevier Ltd.

Sintese e caracterização do compósito TixOy- MWCNT para fotodegradação de carbaril

In this study, a composite of titanium oxide (TixOy) and carbon nanotubes multi-walled (MWCNT) was synthesized on a titanium substrate using the sol-gel method. The electrode obtained (TixOy-MWCNT/Ti) was used to the photodegradation of Carbaryl. The morphology and structure of the TixOy-MWCNT composite were characterized by scanning electron microscopy (SEM), scanning electron microscopy by field emission (FEG-SEM) and X-ray diffraction (XRD). The electrode was evaluated for degradation of Carbaryl (0.9 mmol L-1) in phosphate buffer pH 6, and using chronoamperometry by applying a potential of +1,5 V for 1 h. Using the Ultraviolet-Visible test, the absorbance at 220 nm was collected every 15 min to calculate the percentage of Cabaryl´s degradation. Can be evaluated that the Carbaryl degradation using the TixOy-MWCNT/Ti electrode was 22% more efficient when compared with the electrode without the presence of titanium oxides (MWCNT / Ti)
