ABSTRACT:
A process for coating inorganic substrates, especially metallic or metalloid substrates, sintered metal carbides and carbon materials with carbides, nitrides and/or carbonitrides, using certain nitriles as sources of carbon and nitrogen, is described. High deposition rates and smooth coatings of good to very good adhesion are achievable by this process.
