ABSTRACT:
A wear resistant article, such as a cutting tool. A cemented carbide substrate is coated with a composite ceramic coating having at least two phases. The first phase is a continuous oxide matrix layer 0.1-20 microns thick of oxides of alumina, zirconia, or yttria. At least one discontinuous second or additional phase of oxides of aluminum, zirconium, or yttrium, or solid solutions thereof, is dispersed as discrete particles within the matrix layer. The additional phase material is different from the matrix material.
