Abstract

In this paper, six technologies have been used to implant N+ into 0Cr13Ni9Ti SS, which is a kind of general turbine material in China, and their comparative experiments have been done to get a much better technology of modification of cavitation damage. The results show that the ability of cavitation resistance for 0Cr13Ni9Ti SS by N+ ion implantation can reach more than 2 times of that before treatment. Meanwhile, for various technologies of N+ ion implantation the changes of the surface compounds and their organizations are analysed by X-ray diffraction (XRD).
