ABSTRACT:
A drill bushing or similar article, such as a pump seal, having a hardened body of steel and a thin coating of tungsten carbide distributed throughout a matrix of nickel chrome which provides a metallurgical bond to the steel body and a metallic bond to the particles of tungsten carbide. The drill bushing or similar article will have the wear characteristic of the solid tungsten carbide article, but would retain the coefficient of expansion characteristic of steel with the steel body eliminating the brittleness experienced in solid tungsten carbide articles.
