摘要:

采用失重法,电化学测试技术,X射线衍射 (XRD) 并结合扫描电镜 (SEM) 研究了模拟工业环境下直流电场对金属Zn在30 d内腐蚀行为的影响。结果表明,模拟工业环境下,在一定暴露时间内,直流电场强度越大,Zn的腐蚀速率越大。随着直流电场的介入,Zn的阴极还原过程与阳极溶解过程均有提高,从而腐蚀速率增加。直流电场对于Zn腐蚀行为的影响本质上归结于电场对溶液中离子分布的影响,进而改变了腐蚀产物的结构,促进了腐蚀过程的进行。

关键词 ： Zn, 直流电场, 大气腐蚀, 腐蚀产物, 离子迁移

Abstract：

The effect of a direct current (DC) electric field on the corrosion of Zn exposed in a simulated industrial environment for a period of 30 d was studied by using weight loss and electrochemical tests, XRD and SEM techniques. The results show that the corrosion rate of Zn increased with the increase of DC electric field intensity. With an applied DC electric field, the cathodic reduction process and the anodic dissolution reaction process of Zn in the simulated industrial environment can be accelerated. The influence of the DC electric field on the corrosion behavior of Zn can be attributed to that the distribution of ions in the solution may be altered by the electric field, thus, it can change the reaction site of the formation and also the structure of the corrosion product. Then, the corrosion rate of Zn in the simulated industrial environment can be increased.

Key words： zinc direct current (DC) electric field atmospheric corrosion corrosion product ion migration
