S1106-1-4 Improvement of wear-resistance of TiAlN film by addition of Cr and Si

Abstract

The tribological performance of TiAlN film doped with minor constituents of Cr and Si elements was investigated. The tribological characteristics were evaluated by a ball-on-block sliding test against an alumna ball. The friction coefficient was around 0.7, which was not much different from that of TiAlN film, and the wear amount was found to be around a half compared with TiAlN film. The film life was evaluated by a ring-on-block sliding test against an aluminum alloy. The film life of TiAl(Cr,Si)N film was very short compared with TiAlN film.
