<p>9444-18 A method of forming a layer of a nitride or carbonitride of titanium, vanadium or the like on the surface of an article to be treated includes disposing a treating material composed of refractory powder, powder of a metal or alloy of a nitride forming element and a halide powder, and the article to be treated in a fluidized bed furnace, ancl introducing a nitrogen-containing gas into the furnace under heated conditions to fluidize the treating material, thereby effecting the surface treatment. This method provides a nitride or carbonitride layer having a smooth surface and a uniform thickness rapidly and safely without using hydrogen and a halogen vapor. The method is much safer than that of prior art. TC6011-2</p> |
