Abstract
A process for producing diffusion layers of carbides, nitrides and/or carbonitrides on metallic or metalloid substrates, using certain nitriles as sources of carbon and nitrogen, is described. Uniform and well-adhering diffusion layers can be produced in short reaction times by means of this process.
