离子注入技术在水轮机材料空蚀改性中的应用

Effects of ion implantation on surface modification of cavitation damage for turbine materials

摘要: 本文综述了离子注入技术及其在金属材料表面改性中的应用，分析了水轮机材料空蚀破坏的机理（将空蚀看作是疲劳、硬度和磨损的一种交变力的作用），介绍了离子注入技术对水轮机材料的空蚀改性有较好的作用．

Abstract: In this paper, ion implatation technique and its some applications to surface modification of metals are introduced,and mechanisms of cavitation damage of turbine are explained as a combination of hardness,wear,fatigue and some other factors. Therefore,it can be got that ion implantation has much better effects on surface modification of cavitation damage for turbine materials.
