Vadiraj and Kamaraj present a study of fretting wear tests of surface modified biomedical titanium alloys in medical grade devices used for biomedical implants in hips, knees, and other joints. They consider the poor resistance to sliding wear or fretting wear, which is the primary drawback of titanium alloys, and the surface modification of these alloys to maintain superior quality and improved performance, focusing on Ti-6Al-4V and Ti-6Al-7Nb alloys and the surface modification processes of PVD TiN coating, plasma nitriding, nitrogen ion implantation, laser nitriding, and thermal oxidation.
