| 摘 要： | 通过模拟闭塞腐蚀电池试验及室内间浸挂片试验,对常用的Ni-Cr系和Mn系两类低合金船体结构钢的耐点蚀性能作了比较.短期挂片的结果表明,Ni-Cr系钢的耐点蚀性能优于Mn系钢;而模拟长期挂片条件的闭塞电池试验结果则表明,Ni-Cr系钢的耐点蚀性能比Mn系钢差.在涂层保护下,Ni-Cr系钢的点蚀诱发孕育时间比Mn系钢长很多.表现为实船使用中Ni-Cr钢的耐蚀性一直优于Mn系钢.

| Abstract: | The pit corrosion resistances of nickel - chromium series and manganese series low alloy structural hull steels were compared by simulating occluded corrosion cell tests and interval laboratory immersion corrosion tests. The short - term immersion corrosion results showed that in early pit propagation stage, the rates of pitting propagation of nickel - chromium steels were slower than those of manganese steels. However, the results of the simulating occluded corrosion cell tests showed that the pitting resistance of nickel - chromium steels were lower than that of manganese steels when simulating long - term immersion corrosion test. However, pitting initiation stage of nickel - chromium steels with coating is much longer than that of manganese steels with coating. Therefore the resistance of nickel-chromium steels is bigger than that of maganese steels in practical use. |
