A hard faced article comprising an iron or steel substrate having on the surface thereof a weld deposit composed of a solidified iron or steel matrix containing a hard facing material comprising chemically combined vanadium and carbon having tungsten composition wherein said chemically combined vanadium and carbon with tungsten composition consist essentially of a solid solution of vanadium, tungsten and carbon composition and is substantially uniformly distributed throughout said solidified iron or steel matrix, said composition consisting essentially of at least one vanadium carbide with tungsten in solid solution with each vanadium carbide in an amount from about 10% by weight up to solid solubility limit of tungsten in each vanadium carbide.

Hard faced article

Method for hard-facing substrates is disclosed using a hard facing material consisting essentially of at least one vanadium carbide. In a particular embodiment of the invention tungsten is present in the hard facing material in solid solution with vanadium carbide.

Hard facing of metal substrates

A rod for hard-facing substrates is disclosed using a hard facing material consisting essentially of at least one vanadium carbide. In a particular embodiment of the invention tungsten is present in the hard facing material in solid solution with vanadium carbide.

Hard facing rod

The present invention is a process for making shaped, dense, hard, fine grain tool quality tungsten carbide by the interaction of tungsten, carbon and cobalt during a single heat treatment to form WC + Co compositions. The interaction occurs in situ without the aid of applied pressure. The interaction produces wares of high density with excellent mechanical and cutting properties.
