HIGH HARDNESS FINE GRAINED TUNGSTEN-CARBON ALLOYS AND PROCESS FOR MAKING SAME

摘要

Extremely hard, fine grained tungsten/carbon alloys are described which are produced by thermochemical deposition. The alloys consist primarily of a mixture of a substantially pure tungsten phase and at least one carbide phase wherein the carbide phase consists of W2C or W3C or a mixture of W2C and W3C. The disclosed tungsten/carbon alloys are free of columnar grains and consist essentially of extremely fine, equiaxial crystals. Also disclosed is a method of producing the disclosed material.
