| 摘 要： | 对AISI 321和AISI 304不锈钢进行了低温离子渗氮,其表面获得了均匀的渗氮层即白亮层。与未经渗氮的钢相比,经离子渗氮的钢表面硬度和耐磨性显著提高,而耐蚀性也并不降低;与经传统的盐浴氮碳共渗的钢相比,经离子渗氮的钢的耐磨性和耐蚀性也均有所提高。对经低温离子渗氮的AISI 321纲渗层进行了XRD分析,发现试样的谱峰明显向低角度偏移。 |

| Abstract: | AISI 321 and AISI 304 stainless steels were plasma nitrided at low temperature, and uniform nitrided cases, namely ,white layers ,were developed on their surfaces. The two steels subjected to low temperature plasma nitriding were superior to that without being nitrided in the surface hardness and wearability and meanwhile retained the same corrosion resistance, and also superior to that subjected to conventional liquid nitroearburizing in the wearability and corrosion resistance. The low temperature plasma nitrided case of 321 stainless steel was analyzed by XRD, and the analysis found that the diffraction peak had evidently moved in low-angle region. |
| Keywords: | stainless steel corrosion resistance plasma nitriding |
