为了系统地研究65Mn、35Cr2Ni3MoV 和 AF1410三种金属材料在模拟海洋环境中的耐蚀性能，进行了人造海水全浸测试、盐雾／干／湿交替循环测试和电化学测试。结果显示，这三种金属在三项测试条件下的腐蚀速率排序均为65Mn＞35Cr2Ni3MoV＞AF1410。电化学阻抗谱（EIS）模拟分析结果表明，三种金属裸材表面氧化膜的数量排序为35Cr2Ni3MoV＞65Mn＞AF1410，氧化膜的致密性排序为 AF1410＞＞35Cr2Ni3MoV＞65Mn，氧化膜的平整性排序为35Cr2Ni3MoV＞65Mn＞AF1410。
The corrosion resistance of 65Mn,35Cr2Ni3MoV and AF1410 in simulated marine environment was systemically characterized through full immersion experiment in artificial sea water,salt fog/wet/dry alternate circulation experiment and electrochemical test.The results showed that the corrosion rate of the three materials followed the order of 65Mn > 35Cr2Ni3MoV > AF1410.The electrochemical impedance spectroscopy (EIS) simulation results showed that the amount of the oxidation film on the bare metal material surface followed the order of 35Cr2Ni3MoV > 65Mn > AF1410,the density of the oxidation film followed the order of AF1410 > >35Cr2Ni3MoV> 65Mn,and the smoothness of the oxidation film followed the order of 35Cr2Ni3MoV> 65Mn >AF1410.
