C23C 8/36 using ionised gases, e.g. ionitriding
Full Title
Solid state diffusion of only non-metal elements into metallic material surfaces (diffusion of silicon C23C10/00); Chemical surface treatment of metallic material by reaction of the surface with a reactive gas, leaving reaction products of surface material in the coating, e.g. conversion coatings, passivation of metals (C23C14/00 takes precedence) > using gases (C23C8/36 takes precedence) > using ionised gases, e.g. ionitriding
