<p>This hard coating is a multilayer film comprising two or more of the following layered in alternation: first coating layers (24) comprising a Ti1 - a - bCraMb nitride, oxide, carbide, carbonitride, or boride, where M includes at least one of silicon, vanadium, and tungsten; and second coating layers (26) comprising silver. One atomic proportion (a) for the first coating layers (24) is between 0.2 and 0.4, inclusive; the other atomic proportion (b) for the first coating layers (24) is between 0.1 and 0.3, inclusive; the layering pitch (d3) of the first coating layers (24) and the second coating layers (26) is between 0.2 and 100 nm, inclusive; and the total thickness (D) is between 0.2 and 10.0 µm, inclusive. The coefficient of friction and cutting resistance can thus be reduced by the inclusion of silver in the coating, and a hard coating that exhibits superb lubricity and resistance to seizure can be obtained.</p> |
