摘要： 对水轮机用0Cr13Ni5Mo不锈钢及其精炼合金在蒸馏水和模拟长江水中进行了旋转圆盘仪空蚀和冲蚀以及二者组合的多相流损伤实验,并与普通13-4不锈钢进行对比分析·结果表明,精炼工艺改进后的0Cr13Ni5Mo不锈钢晶粒内部的铁素体组织得到了细化,抗冲蚀和多相流损伤能力明显高于原合金和13-4不锈钢·3种不锈钢的冲蚀、空蚀与冲蚀联合作用损伤累积失重-时间曲线均呈直线关系,空蚀和冲蚀联合作用对材料造成的损伤明显高于空蚀和冲蚀单独作用·

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.
