| 摘 要： | 简单介绍了新开发的ＣＨ钝化工艺及其特点，用恒电量技术对比测试了ＣＨ钝化工艺形成的经膜和常规钝和化膜，ＣＨ钝化膜的Ｒｐ、Ｒｆ值大，Ｃｄ、Ｃｆ值小；再应用循环伏安法在－１．０２－－１．６８Ｖ范围进行测试，发现ＣＨ钝化膜的循环伏安图经１０次循环后仍与第一次的一样。两种测试说明了ＣＨ钝化膜常规钝化的耐蚀性高。两种电化学测试的结果与其它方法的结果的一致。

| Abstract: | Corrosionresistant performance of two kinds of passive film on the Zinc coating was analyzed by means of testing their specific properties with constant quantity charging technique and electrochemical cyclic voltammetary. It is confirmed that passive film formed from CH technology, which is developed lately, is more compact and complete, and has a higher resistance to corrosion. |
