摘要: 

通过循环盐雾腐蚀实验模拟镀锌钢在酸雨大气环境中的腐蚀过程。采用腐蚀质量损失测试、扫描电镜 (SEM)、能谱仪 (EDS) 和电化学技术分别对腐蚀48,84,132,180和228 h的镀锌钢试样进行测试分析,得到腐蚀动力学规律、腐蚀产物成分、锈层截面形貌以及表面锈层的电化学特性。研究了锈层对镀锌钢在酸雨条件下大气腐蚀的影响。动力学分析表明,腐蚀过程中镀锌钢的表面形成了具有较好保护性的锈层；电化学测试结果表明,锈层的保护性呈现随腐蚀时间的延长先增强后减弱的变化过程。

Abstract：

The evolution of corrosion process of hot-dip galvanized steel in a simulated acid rain atmospheric environment as a function of time was investigated by corrosion mass loss test, scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS) and electrochemical techniques.<br>Consequently, corrosion kinetics, the surface and cross-sectional morphology and composition as well as electrochemical characters of corrosion products were acquired. The influence of the rust layers on the atmospheric corrosion of hot-dip galvanized steel was studied. According to the corrosion kinetics the rust layers can well protect the hot-dip galvanized steel from corrosion. The results of electrochemical measurement further illustrate that the protective effect of the rust layers is firstly enhanced, and then weakened as the corrosion time increases.
Key words： hot-dip galvanized steel    simulated acid rain    electrochemical technique    atmospheric corrosion
