Abstract

Due to their excellent properties, Ti-Al-N coatings have become attractive for biomedical applications. In this paper, friction and wear properties of Ti_1-xAl_xN films having various aluminum contents, x, have been studied. Adhesion was measured by the scratch test technique; friction was carried out by a pin-on-disk tribometer using an animal bone-pin as counterpart and Ringer's solution as simulated body fluid; and wear mechanisms were identified by SEM and EDS. It was found that the coating with x = 0.41 exhibited the highest COF, conserves its integrity as a coating, and causes the lowest wear on the bone in Ringer's solution.

Keywords: Sliding wear; PVD coatings; corrosion wear; biological aspects.
