ABSTRACT:
A multilayer coating of metal-cutting tools is composed of alternating layers of two components. One of these is a nitride or carbide of a metal of group IV. The other is a nitride, carbide, boride or silicide of a metal of group VI. The layer thickness of the group IV metal compound is from 0.05 to 0.5 .mu.m, and the layer thickness of the group VI metal compound constitutes 15 to 40 percent of the layer thickness of the group IV metal compound. The multilayer coating is preferably intended for application to metal-cutting tools used for machining high-alloyed materials.
