Abstract: Cavitation-abrasion behavior of 0Crl3Ni5Mo steel and its refined alloy in multiphase flow was investigated with a rotary disc tester in distilled water and simulated Yangtze river water, and the results were in contrast with those from 13-4 stainless steel. The microstructures and the eroded surfaces observed by SEM and electro-microscope showed that in the refined 0Crl3Ni5Mo steel the ferrite grain size is smaller and the resistance to abrasion or cavitation-abrasion is obviously higher than the original steel and 13-4 stainless steel. Their accumulative mass losses due to abrasion or cavitation-abrasion all exhibit linearly time-dependent, and the integrated cavitation-abrasion action did more serious damage to the material used than single cavitation erosion or abrasion.
