本文采用双层辉光离子渗金属技术进行了普通碳钢的镍铬共渗研究。选择源极电压,工作气压,阴极电压,极间距等工艺参数为因子进行了正交试验。以高合金浓度及大的渗层厚度为目标,确定了最佳工艺条件。试验结果表明,放电条件不同时,表面浓度及渗层厚度在相当大的范围内变化。进行工艺优化不仅能保证渗层质量,而且能显著提高合金元素的利用率。
In this paper, double glow plasma infiltration metal technology for ordinary carbon steel Ni-Cr permeation studies. Select the source voltage, working pressure, cathode voltage, pole spacing and other process parameters for the orthogonal factor test. With the high alloy concentration and large layer thickness as the goal, the best process conditions were determined. The experimental results show that the surface concentration and the thickness of the diffusion layer vary within a relatively large range under different discharge conditions. Process optimization can not only ensure the quality of the infiltration layer, but also significantly improve the utilization of alloying elements.
