|Abstract:||Titanium and its alloys are employed for many biomedical applications. One of the reasons of this success is related to the high biocompatibility of this material. As a matter of fact, its spontaneous capacity to create a passivation film of titanium oxide on the surface results in low amount of metal ions release in vivo and in a high resistance against corrosion. Moreover, the absence of Ni in its alloys represents an important issue in the evaluation of its biocompatibility, as compared to CoCrMo. As a matter of fact such an element is recognized as allergenic and cancerogenic agent. Nevertheless, the poor wear resistance of the Ti-oxide film keeps Ti from being employed in tribological applications. The present work investigates the possibility to apply surface treatments to the titanium in order to increase its wear resistance.|
