摘　　要： 将铬离子源引入常规离子氮化炉,在铬、氮离子淹没条件下轰击不锈钢,采用金相显微镜、磨损试验机和电化学工作站等分析了不同工艺条件下渗层的显微组织、耐磨性和耐蚀性.结果表明:与未经处理的不锈钢相比,经氮、铬离子淹没离子轰击处理的不锈钢的耐磨性提高2-5倍;处理后不锈钢的耐蚀性虽有所下降,但与常规的离子氮化试样相比仍明显改善. In this paper, chromium ion was introduced in the conventional ion-nit.tiding stove to carry out the ionic bombardment of stainless steel by nitrogen and chromium ion immersion. An optical microscopy, an abrasion test device and an electrochemistry workstation were then adopted to investigate the microstructure, wear resistance and corrosion resistance of the samples in different processing conditions. The results show that the wear resistance of the stainless steel with ionic bombardment processing is 2 - 5 times that of the untreated sample, and that the bombarded stainless steel is of a little reduction in corrosion resistance, as compared with the original stainless steel. However, as compared with the traditional ion-nitriding stainless steel, the corrosion resistance is greatly improved.
