Abstract (en)
[origin: US4728579A] A wear resistant, coated, metal carbide body comprising a metal carbide basic body, a metallic intermediate layer and at least one metal-free hard substance layer; wherein the metallic intermediate layer comprises molybdenum and/or tungsten, has a thickness of 0.1 to 2 mu m and is applied to the metal carbide basic body by means of a physical vapor deposition process, preferably by direct cathode sputtering. During the application of the intermediate layer, the metal carbide basic body has a temperature from 200 DEG to 600 DEG C.
