<p>A hard coating superior in wear resistance and in oxidation resistance and also a hard coating superior in high-temperature anti-friction performance and oxidation resistance over the conventional coating film are provided. One of the typical hard coating excellent in wear resistance and oxidation resistance, which comprises a composition represented by the formula: (Al a ,M b ,Cr 1-a-b ) (C 1-e N e ) (where M represents W and/or Mo, a, b and e that represent atomic ratios of Al, M and N, respectively, satisfy the following relations):
0.25 ‰¤ a ‰¤ 0.65,
0.05 ‰¤ b ‰¤ 0.35, and
0.5 ‰¤ e ‰¤ 1</p> |
