65Mn、35Cr2Ni3MoV和AF1410在模拟海洋环境中的耐蚀性
Corrosion Resistance of 65Mn, 35Cr2Ni3MoV and AF1410 in Simulated Marine Environment
摘 要
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。

Abstract
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.
