摘要:
对典型钢(碳钢Q235和耐候钢09CuPCrNi)在海洋大气(麦岛)和污染海洋大气(团岛)环境中进行了2年的暴露腐蚀实验,并测试了其环境的大气污染因子。结果显示典型钢在团岛的腐蚀明显地比麦岛重,团岛的氯离子浓度几乎是麦岛氯离子浓度的3倍。讨论了海洋大气和污染海洋大气对典型钢的腐蚀作用的差异。

Corrosion of steels by clean and polluted marine atmosphere
Abstract:
Typical steels (mild steel Q235 and weathering steel 09 CuPCrNi) were exposed to polluted (Tuandao) and unpolluted (Maidao) marine atmosphere for two years. The result shows that corrosion of typical steels in Tuandao is more serious than that in Mardao, and that chloride content in Tuandao is three times higher than that in Maidao. The difference of the effects of polluted and unpolluted marine atmosphere on corrosion of steels were discussed.
Key words:  typical steel  pollution factor  marine atmosphere corrosion
