苏联柴油机厂采用合金灰铸铁(C2.8～3.5%,Si1.6～2.0%、Mn0.8～1.2%,P0.1～0.25%,S0.05～0.12%,Cr0.3～0.7%,Ni0.3～0.7%)来制造船用柴油机气缸套,这种铸铁的强度和耐磨性均不能满足技术要求。为提高气缸套使用性能,作者同该厂合作对各种金属基体组织的蠕墨铸铁进行研究与试 Soviet Union Diesel Engine Factory uses alloy gray cast iron (C2.8 ~ 3.5%, Si1.6 ~ 2.0%, Mn0.8 ~ 1.2%, P0.1 ~ 0.25%, S0.05 ~ 0.12%, Cr0.3 ~ 0.7% Ni0.3 ~ 0.7%) to manufacture marine diesel engine cylinder liner, the strength and wear resistance of such cast iron can not meet the technical requirements. In order to improve the performance of cylinder liner, the author cooperated with the factory to study and test vermicular cast iron of various metal matrix organizations
