【Abstract】 The combination technology of plasma nitriding and depositing TiN film by multi-arc ion plating under higher vacuum (10 -1Pa) on stainless steel substrate is introduced. The structures and composition of the coating are analyzed by X-ray diffraction, optical microscope, electron probe. The results show that the compound layer of 10μm is formed in the surface of stainless steel after plasma nitriding at 380℃ for 3 hours. The hardness of the coating,in which the main phase is TiN,obtained by plasma nitriding and multi-arc ion plating is 2100-2400 HV.更多还原
