介绍了双层辉光离子渗金属多元共渗的研究结果。讨论了渗层组织和成分,渗层厚度与工艺参数的关系。试验表明共渗层厚度取决于共渗温度、保温时间和试样材料,其变动范围为0～500 μm,钢的共渗层中的合金元素含量可在0～90%的范围内变动。此外,还列举了双层辉光离子渗金属多元共渗在碳钢钢板及碳钢零件上的应用。 The research results of double glow ion infiltration metal multivariate permeation were introduced. The relationship between the structure and composition of the layer, the thickness of the layer and the process parameters is discussed. The experimental results show that the co-diffusion layer thickness depends on the co-infiltration temperature, the holding time and the sample material. The variation ranges from 0 to 500 μm. The alloying elements in the co-diffusion layer can vary from 0 to 90%. In addition, also lists the double glow ion infiltration metal multivariate co-infiltration in the carbon steel and carbon steel parts on the application.
