Abstract

PURPOSE:To form a metallic carbide layer having high hardness, heat resistance and corrosion resistance on the surface of a base material by diffusing and sticking carbon on the base material then causing specific metals to react thereby forming the hard metallic carbide layer thereon. CONSTITUTION:A hydrocarbon soln. such as kerosene is coated on the surface of a base material 1 to be applied with surface treatments, and an electrode is opposed to the coating surface, then electricity is discharged from said electrode. The volatile contents of the kerosene are scattered away, and only the fixed carbon remains. Said carbon is diffused into the material 1 by the high temp. of the discharge, thus forming a carbon film 2. Thereafter, metals such as Fe, Si, W, Ti, V, Cr or the like are diffused in the film 2 and are caused to react with said film by a method such as ion plating, plasma plating or the like, whereby the carbide layer 3 of said metals is formed. The hardness, heat resistance and corrosion resistance of the surface of the base material are improved by said metallic carbide layer.
