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
