Abstract
A method is disclosed for producing a Wc-Co-Cr alloy which comprises alloying a mixture consisting essentially of in percent by weight of from about 85 to about 90 tungsten carbide, wherein the particle size of the tungsten carbide is less than about 1 micrometer in diameter, from about 9 to about 11 cobalt metal powder, wherein the particle size of the cobalt is from about 1 to about 5 micrometers in diameter, and from about 3.5 to about 4.5 chromium wherein the chromium is provided as chromium carbide to produce a Wc-Co-Cr alloy the alloy capable of being used as a coating wherein the hardness of the coating is from about 1060 to about 1240 DPH carbide hardness and from about 870 to about 980 DPH matrix hardness and wherein the roughness is from about 190 to about 200 AA.
