  • Abstract
    The tribological properties of a Co-Cr thin film were greatly improved by surface oxidation. According to surface analyses, a Cr-rich oxidized region in which Cr is oxidized to Cr2O3 was formed near the surface of the film. This region plays an important role in improving the mechanical durability of the film. However, when the oxidation is carried out for a long time, a thick Co-rich oxidized region grows on the Cr-rich oxidized one. As a result, the durability deteriorates
