摘要：

To evaluate the effect of heat treatment on the cavitation erosion resistance of stainless steel, an experimental investigation is carried out using a cavitating jet test apparatus complying with the ASTM G134 standard. The jet pressure is 30 MPa and the cavitation number is 0.014. Specimens made of stainless steel SUS630 are aged at different temperatures. Prior to cavitation erosion experiment, the mechanical properties of the specimens are obtained through an inverse analysis method in conjunction with the indentation test. The material's cavitation erosion resistance is represented by the reciprocal of the maximum cumulative mass loss rate. The correlation between cavitation erosion resistance and mechanical parameters is pursued. The variation of cumulative mass loss with the exposure time under cavitating jet impact demonstrates that the rise of aging temperature impairs the cavitation erosion resistance of SUS630. The overall cumulative mass loss rate of SUS630 is lower than that of SUS316L. The correlations between cavitation erosion resistance and mechanical parameters are evident. The parameter of microhardness exhibits the most explicit relevance with respect to the cavitation erosion resistance.
