The results showed that, with the inhibitor YWY, a compact overlayer film was obtained on the metal surface and YWY showed cathodecorrosion inhibitor.
实验表明，该缓蚀剂可与碳钢表面螯合形成致密的覆盖膜，表现出明显的阴极型缓蚀剂特征。

Cathode protection is one of the most effective methods for suppressing corrosion, while reasonable design, installation and maintenance are very necessary.
阴极保护是抑制腐蚀最有效的方法之一，但需合理设计、安装和维护。

The sulfites all can make potential of steel sharply shift negatively and inhibit the cathode process in corrosion.
