.... Whenever a compound layer is formed, it will contain carbon and/or carbonitrides as well as nitrides. This phenomenon is explained by the high solubility of carbon in nitrides and especially in ε-type (Fe 2-3 N) nitrides. It is common to distinguish between nitriding and nitrocarburizing on the basis...
