During the nitriding treatment, the diffusion of nitrogen in the steels causes the transformation of initial carbides into nitrides. During this transformation, carbon is released into the ferritic matrix. The experimental study has highlighted that the decarburization of the nitride layer occurs regardless of the type of nitriding and could reach 20% when the nitriding surface is not composed of compound layer This decarburization is induced by the reaction of the carbon released during the transformation of the cementite, with the hydrogen produced by the decomposition of ammonia to give a carburized species ?, this reaction occurs as long as any compound layer exists at the surface of the sample. This carbon redistribution has an influen...
