| 摘 要： | 本文通过大气环境暴露试验,研究了在青岛海洋大气环境中暴露10年5周期的4种磷钒系耐候钢的腐蚀规律。结果表明,四种耐候钢的腐蚀速率的关系为:10CrPV10CuPV10MoPV08PV,耐侯钢的耐蚀性与添加元素类别和添加量相关。平均腐蚀深度数据拟合结果表明,A值大小顺序为:10CrPV10CuPV10 MoPV08PV,而n值的顺序是:10CuPV10CrPV10MoPV08PV。

| Abstract: | In this paper, the corrosion law of four P-V weathering steels exposed to marine atmosphere in Qingdao for 10 years including 5 cycles was studied. It turned out that the relationship of the corrosion rate of four weathering steels as follows： 10CrPV＆lt;10CuPV＆lt;10MoPV＆lt;08PV, and corrosion resistance of weathering steels was connected with the category and amount of added element. Meanwhile, the results of average corrosion depth showed that value of A was arranged as follows： 10CrPV＆lt;10CuPV＆lt;10MoPV＆lt;08PV, and value of n was arranged as follows： 10CuPV＆lt;10CrPV＆lt;10MoPV＆lt;08PV. |
