摘　　要：通过显微夹杂物分析、室内间浸挂片试验和相关的电化学性能测试,对12CrNiMo钢和35Cr钢的耐海水腐蚀性能进行了比较分析,结果表明:在海水介质中,12CrNiMo钢比35Cr钢的耐海水腐蚀性能要好。两种钢化学成分及夹杂物类别、形态、分布和数量上的不同,是造成两者耐海水腐蚀性差异的主要原因。The corrosion resistance of 12CrNiMo and 35Cr in sea water was compared and analyzed by means of micro-inclusion examination, laboratory immersion tests and electrochemical tests. The results showed that 12CrNiMo steel was less corroded than 35Cr steel. The main reasons of the different corrosion resistance of these two steels resulted from differences in the chemical composition as well as the type, morphology, distribution and amount of micro-inclusions.
