Effects of Cr-Mo Infiltration Source Cathode Different Mixing Proportion on the Thickness of Alloy Layer
Based on the plasma nitriding technique, the double glow plasma surface metallurgy (DG-PSM) technology was developed. This technology is also known as the Xu-Tec Process which utilizes solid metallic elements such as Ni, Cr, Mo, W, Ti, Al, Nb, Zr and their combinations to accomplish plasma surface alloying. Mo-Cr strengthened coating was prepared on the surface of low carbon steel Q235 by this technology. This coating is used to high wear resistant cold die LD steel. By experiment of the three different prescriptions in source cathode, the effect of source cathode composition on the coating has been studied. The technological parameters were as follows ：The ratio of Mo and Cr were 2 ：1 ，4 ：1 and 6 ：1. The work-piece material is Q235 low carbon steel. Holding time is 4h. Holding temperature 1050 ℃.Source cathode structure was threadiness. The consequences of composition analysis and microstructure observation results show that, most approaches the purpose of this research is the ratio of Mo and Cr is 6:1 ，and the alloyed layer has stronger adhesion with substrate.
