    摘要: A cutting tool or a wear-resistant mechanical part comprises: a substrate of WC, Co, TiC, and TaC with or without an inner coating layer of TiC, TiN or TiCN; an intermediate layer of a titanium oxycarbide formed on the surface of the substrate or the inner coating layer by carrying out a reaction thereon at a temperature of 800.degree. to 1,200.degree. C. of a halide of titanium, hydrogen, and carbon monoxide or carbon dioxide or a mixture thereof; and an outer coating layer of aluminum oxide formed on the outer surface of the intermediate layer. The thicknesses of the inner layer, the intermediate layer , and the outer coating layer are of the order of 0.5 to 20 microns, 0.5 to 20 microns, and 0.5 to 10 microns, respectively.
