对浸入海水中的锌参比电极以恒电流方法进行阳极氧化,在不同温度、盐度、流速环境条件的海水中,测量锌电极电位随时间的变化情况。结果表明,阳极氧化法可以提高海水中锌参比电极电位的稳定性。扫描电子显微镜(SEM)和X射线衍射(xRD)分析表明,锌参比电极表面产物主要为氢氧化锌和氧化锌。

The zinc immersed in seawater was anodized by galvanostatic polarization. The potential of electrode immersed in seawater was measured in different environments. The results were compared with those of the unanodized zinc electrode. The results showed that changes of the potential of anodized zinc electrode were not remarkable. The anodic film was studied with scanning electron microscopy (SEM) and X-ray diffraction (XRD) and that the main corrosion products of zinc are Zn(OH)2 and ZnO.
