摘要： 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.

摘要： A nitride or carbonitride layer is formed on the surface of a metal material as follows: A treating agent composed of a refractory powder of alumina or the like and a powder of a metal for forming a nitride or a carbide or an alloy thereof is disposed in a fluidized bed furnace; the treating agent is fluidized to form a fluidized bed by introducing an inert gas; the fluidized bed furnace is heated to a temperature of not higher than 700.degree. C.; an activator of a halogenated ammonium salt is intermittently supplied into the fluidized bed at a rate of 0.001 to 5 wt %/hour based on the total amount of the treating agent; and the metal material to be treated is disposed in the fluidized bed during or after any of the above steps. For example, a nitride layer composed of only a metal for forming a nitride which contains almost no Fe--N is formed on the surface of iron steel even at a temperature as low as not higher than 700.degree. C. The layer is very hard and efficient in wear resistance, and the toughness of the base metal is hardly lowered.
