| 摘 要： | 通过极化试验与模拟闭塞腐蚀电池试验对常用的两类低合金船体结构钢耐蚀性能做了比较，并结合实船使用情况对两类钢的耐蚀性能做了较全面的评价。结果表明，Ni-Cr系钢的点蚀诱发敏感性低于Mn系钢；在模拟长期挂片时Ni-Cr钢的点蚀扩展速率反比№钢大，而实船使用情况是Ni-Cr系钢的耐蚀性能远比Mn系钢好。

| Abstract: | Pitting resistance of two widely used types of low alloy steels (Ni-Cr and Mn) was compared by polarization test and simulating occluded corrosion ce ll test. The results showed that the susceptibility of nickel-chromium steel to pitting initiation was smaller lower than that of manganese steels. The rate of pitting propagation of Nickel-chromium steel was greater than that of manganese steels. In overall, The resistance of nickel-chromium steel was better than that of manganese steels in real case. |
