Description
Summary:Small fitment parts are produced from corrosion-resistant steels that are known to possess low tribological properties. This problem can be solved by nitriding. Nitriding increases the strength, hardness, wear resistance, and score resistance of steels with a nitrided layer. The traditional nitriding process possesses substantial disadvantages, i.e., a high duration of diffusion saturation, brittleness of the hardened surface layer, difficulties in saturation of easily passivating materials, and the impossibility of fabricating a layer of the same thickness over the whole of the treated surface of a part with complex configuration. In addition, successful nitriding of corrosion-resistant steels requires additional depassivation of the surface, because the dense oxide film lying on the surface of these metals hampers the penetration of nitrogen into them. (Ion nitriding was done on steels 16Kh-VI, 14Kh17N2, and alloy 36NKhTYu.)
