摘　　要：研究了当普通灰铸铁中加入０％～０．３％Ｓｂ系复合孕育所获得的高强度灰铸铁。指出其具有良好的抗汽蚀性，在最佳成分下可比ＨＴ２００延长寿命５０％以上。With the 0%～0.3%Sb being added into general grey iron,the influence of anti-mony on the cavitation erosion resistance of iron is investigated.the results show that thehigh strength grey cast iron obtained by adding Sb-compound inoculants has a good cavita-tion resistance.comparing it with the HT200,the cavitation resistance can be increased morethan 50%.
