Abstract
Due to its mechanical properties and low density, the Ti-6Al-4V titanium alloy is used in hip prostheses. But the tribological behavior of Ti-6Al-4V sliding against ultra high molecular weight polyethylene involves wear degradations. The wear behavior of (Ti-6Al-4V/UHMWPE) couple can be improved by ion implantation of nitrogen. After a characterization study to find the optimal parameters for classic ion implantation, this study presents an analysis of wear behavior in comparison with chemical composition, microhardness and adhesion work for a new implantation technique, plasma immersion ion implantation.
