A Novel Approach for Rapid Evaluating Cavitation Erosion Resistance of Metallic Materials
摘要
For the evaluation of cavitation erosion resistance of metallic materials, it has always been a time-consuming technical problem. This paper innovatively proposed a parameter named cavitation hardening rate to characterize the plastic deformation and work hardening behavior of metallic materials during the cavitation process and then found a positive correlation between cavitation hardening rate and strain hardening index. Finally, the relationship between cavitation volume loss and strain hardening index was obtained, and a simple and rapid evaluation method for cavitation erosion resistance was established.
