“…It was reported that both compressive and tensile residual stresses had a significant effect on the cavitation erosion resistance of the materials. Anatolii et al applied alternating magnetic field treatment to EN8 steel and nickel-aluminum bronze alloy, which resulted in the generation of compressive residual stress in the treated samples [41]. The results showed a significant improvement in the cavitation erosion resistance of the samples with compressive residual stress.…”

In this study, a nanocrystalline layer composed primarily of martensite phase was prepared on the surface of 304 stainless steel. Furthermore, the martensite phase content in the nanocrystalline layer was adjusted by heat treatment at 500 °C and 550 °C, respectively, and the cavitation erosion resistance of the nanocrystalline layer before and after heat treatment was investigated. The results showed that the nanocrystalline layer before and after heat treatment exhibited excellent erosion resistance, with cumulative mass loss of approximately 1/7, 1/5, and 1/3 that of the traditional 304 stainless steel, respectively. The nanocrystalline layer could significantly inhibit the growth of cavitation pits due to the high density of grain boundaries. However, due to the decrease in hardness of the nanocrystalline layer after heat treatment, the propagation speed of cavitation cracks was accelerated, and the cavitation erosion performance of the nanocrystalline layer showed a downward trend.
