摘要:

在湛江高湿热、高盐度、强辐照的热带海洋大气环境下，分别对有氧化皮与无氧化皮的SPHC热轧钢板进行了15，30，90和180 d暴晒实验，研究了氧化皮对SPHC热轧钢板的初期腐蚀行为的影响。采用X射线衍射仪分析了氧化皮与锈层的组成成分，采用扫描电镜观察了腐蚀产物表面和截面的微观形貌，采用X射线能谱仪分析了锈层的元素分布，同时对暴晒后的试样进行极化曲线测试。结果表明，氧化皮的主要组成成分为Fe₃O₄，可以明显减缓钢的早期腐蚀速率。随着腐蚀的进行，氧化皮逐渐转化为锈层，腐蚀产物不断生成，有氧化皮试样与无氧化皮试样的腐蚀行为逐渐趋于一致，腐蚀速率差别较小。氧化皮通过屏蔽作用减缓了钢的早期腐蚀速率，并没有改变腐蚀产物的成分。

Abstract：

The effect of the existed oxide scales on the initial corrosion behavior of SPHC hot rolled steels was assessed via field exposure in tropical marine atmosphere with features of high temperature, humidity, salinity and strong irradiation in a test site at Zhanjiang district for 15, 30, 90 and 180 d. After exposure test, the steel samples were then characterized by means of XRD and SEM with EDS, while their polarization curves were also measured in 3.5% (mass fraction) NaCl solution by Autolab. The results show that the existed oxide scales on the rolled steel consist mainly of Fe₃O₄, which can obviously slow down the initial corrosive rate of the steel. As the corrosion progresses, the oxide scales will gradually transform into the rust layers and corrosion products are constantly generated, the corrosion behavior of the steel samples with and without the existed oxide scales tend gradually to be consistent, and the difference of their corrosion rates turn to be small. In sum, the existed oxide scales can slow down the initial corrosion rate of the rolled steel without changing the composition of corrosion products at all.

Key words： oxide scales atmospheric corrosion SPHC hot rolled steel rust layer
