ABSTRACT:
There is disclosed a process for forming a hardfacing surface including particulate refractory metal carbide by directing a plasma transferred arc against a wear surface of an element and passing a powder comprised of refractory metal carbide particles admixed in a suitable hard metal matrix through the plasma arc to thereby form on the wear surface of the element a hardfacing surface including particulate refractory metal carbide of a thickness of from 0.04 to 0.25 inches.
