摘要
本文运用离子注入技术对四川映秀湾电站水轮机材料ＯＣｒｌ３Ｎｉ９Ｔｉ的空蚀改性效果进行了试验研究，结果表明：Ｎ＋注入后ＯＣｒｌ３Ｎｉ９Ｔｉ的抗空蚀能力可以达到注入前的两倍以上．同时，用Ｘ射线仪分析了试件在不同工艺参数处理后其表面组分的变化．
In this paper six technologies have been used to implant N+into OCr13NigTi.The experimental results show that the resistance to cavitation of OCr13Ni9Ti material being treated can be enhanced to two times.The changes of surface compounds and the organizations of the new material are analysed by using x-ray diffraction(XRD).
