The tribological properties of a Co-Cr thin film were greatly improved by surface oxidation. According to surface analyses, it was found that a Cr -rich oxidized region in which Cr is oxidized to Cr2O3 was formed near the surface of the film by the above treatment. This Cr -rich oxidized region mainly composed of Cr2O3plays an important role in improving its tribological properties.
