摘　　要：利用MEVVA强流金属离子注入机，对65Nb钢进行离子注入采用了Auger电子能潜（AES），X射线衍射（XRD）等表面分析技术，研究了Ti及Ti+Y离子注入后的65Nb钢表面的微结构变化，力学性能实验结果表明，Ti及Ti＋Y离子注入能使材料表面硬度和耐磨性最著提高，且双元离子注入比单元注入效果好。65Nb steel was implanted by MEVVA source ion implantation. The changes in microstructure of 65Nb steel implanted by Ti ions with and without additional Y ions were investigated respectively by using Auger electron spectroscopy and glancing angle Xuray diffraction. The results show that the hardness and wear-resistant of 65Nb steel surface have been obviously improved through implanting Ti and Ti+Y. The effectiveness of dual implantation is better than single implantation. The alloying effect of rare element Y in implanted layer was analyzed and discussed.
