| dc.description.abstract | 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.
