ABSTRACT:
A primary thin hard coating selected from chrome nitride, titanium nitride and titanium carbide, and a secondary thin coating selected from elemental metals and their corresponding alloys capable of dry-plating are provided on a metal material by an ion-plating technique. The secondary thin coating is provided by ion-plating in the absence of an inert gas, such as argon or helium, which is different from conventional methods for ion-plating the elemental metal in the presence of such inert gas.
