WANG Lang-ping, TANG Bao-yin, WANG Xiao-feng, WANG Song-yan, LIU Ai-guo, TIAN Xiu-bo (National Key Laboratory of Advanced Welding Production and Technology, Harbin Institute of Technology, Harbin 150001, China)Abstract: In order to increase the peak depth of nitrogen atoms during the nitrogen plasma ion implantation of Ti-6Al-4V alloy, the rare earth metal yttrium was used to increase the implantation and diffusion depth of nitrogen atoms. In the experiment, the yttrium ions were implanted under the voltage of 20 kV firstly, and then the nitrogen ions were implanted under 30 kV.
