ABSTRACT:
A wear resistant article, such as a cutting tool. A hard refractory substrate is coated with a composite refractory coating having at least two phases. The first phase is a continuous nitride matrix layer 0.1-20 microns thick of nitrides of Si, B, Al, Y, Ti, Zr, Hf, V, Nb, Ta, Mo, or W. At least one discontinuous second or additional phase of nitrides of Si, B, Al, Y, Ti, Zr, Hf, V, Nb, Ta, Mo, or W, or solid solutions thereof, is dispersed as discrete particles within the matrix layer. The additional phase material is different from the matrix material.
