ABSTRACT:
A method for forming a two-layered carbide surface on a ferrous-alloy article containing at least 0.2 percent by weight of carbon. The formation of such a surface is effected by plating the ferrous alloy article with chromium, to form a chromium layer thereon, and heating the thus-plated article in contact with an element of Group Va and/or chromium (a) to diffuse carbon from the ferrous-alloy article into the chromium layer and convert the chromium layer to an intermediate chromium-carbide layer and (b) thereafter to combine carbon in the intermediate chromium-carbide layer with the element (of Group Va or chromium) and thus form a Group-Va-element-carbide layer and/or another chromium-carbide layer on the intermediate chromium-carbide layer.
