Abstract:
A wear resistant article (10), such as a cutting tool. A hard ceramic or cemented carbide substrate (12) is coated with a laminated oxide coating (16) about 0.3-20 microns thick, having at least three ultrathin layers (18, 20, 22, 24, 26). Each layer (18, 20, 22, 24, or 26) is an oxide layer about 0.1-3 microns thick, predominantly of a different material than adjacent layers. The oxide or oxides of adjacent layers may be dispersed as discrete particles (34, 38) within one or more of the layers. A process for producing the article is also disclosed.
