| 摘 要： | 通过锌在红沿河核电站的大气暴露试验,研究了锌在红沿河地区SO2,Cl-含量较高以及高湿的环境条件下的腐蚀规律。试验结果表明锌的腐蚀质量损失与暴露时间呈线性关系。利用扫描电子显微镜、Fourier变换红外光谱仪以及X射线衍射仪对锌表面腐蚀产物进行了分析,进一步分析了腐蚀质量损失与暴露时间呈线性关系的原因,并探讨了锌在SO2,Cl-含量较高以及高湿的环境条件下的腐蚀机理。

| Abstract: | The atmospheric corrosion law of zinc at Hongyanhe nuclear power station with high SO2 concentration, high Cl concentration, and high humidity was studied through outdoor exposure test. The test results showed that the relationship between corrosion weight loss and exposure time of zinc is linear. Corrosion products of zinc surface were analyzed using scanning electron microscope （SEM）, X-ray diffraction （XRD）, and Fourier infrared transform （FI-TR） spectrometer. The reason of corrosion weight loss increased with exposure time was further analyzed. The corrosion mechanism of zinc in high SO2 concentration, high Cl- concentration and high humidity atmospheric environment was discussed. |
