摘　　要：研究了锡对灰铸铁显微组织、机械性能及耐蚀性的影响.结果表明:适量的锡可改善灰铸铁的基体组织,提高其强度和硬度;在质量分数为98%的H2SO4介质中含锡铸铁的耐蚀性能明显优于普通灰铸铁;锡的最佳质量分数范围是0.085%～0.180%.The effect of tin on the microstructure, mechanical properties, and corrosion resistance of gray cast iron is investigated. The results show that an appropriate amount of tin can improve the matrix structure and increase the tensile strength and hardness of gray cast iron. The corrosion resistance of gray cast iron containing tin against the medium with the 98% concentration of H_2SO_4 is apparently superior to the common gray cast iron. The best content range of tin is 0.085%～0.180%.
