C23C8/68 - CPC Classification

Classification description:

Solid state diffusion of only non-metal elements into metallic material surfaces ; 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 using solids, e.g. powders, pastes only one element being applied Boronising
