| titleOfInvention | Method of forming a nitride or carbonitride layer |
| abstract | Abstract of the Disclosure A method of forming a nitride or carbonitride layer on the surface of an iron or iron alloy article, which comprises the steps of: (a) disposing in a fluidized bed furnace a treating agent comprising a refractory powder, a metal powder of at least one selected from the group consisting of chromium, vanadium, titanium and a metal containing at least one of the chromium, vanadium and titanium, and a halide powder; (b) introducing a nitrogen-containing gas into the fluidized bed furnace; (c) heating the fluidized bed furnace; and (d) disposing the article in the fluidized bed furnace during or after the steps (a) to (c). In this method, the article is preferably treated at a temperature not higher than 650°C. The step (c) may precede the step (b). The halide powder may be supplied to the fluidized bed furnace from outside in the form of green compact or a gas. |
