The trivalent chromium passivation film based on zincate plating obtained has compact structure with no obvious crack, and excellent anticorrosion performance. Different compositions are detected from the surface to inner film, the surface mainly contains Cr2O3-Cr3-ZnO compound, the inner (1030 nm to surface) composes of Cr2O3-ZnO-Zn.The forming process of passivation film possibly consists of four steps which are zinc dissolution, basic area appearance, gelatiniform film forming and converting to passivation film.

结果表明：锌酸盐镀锌层的三价铬钝化膜表面结构致密、无明显裂纹，具有较好的耐腐蚀性能；这种钝化膜表层与里层的组成不同，表层的组成为Cr2O3-Cr3-ZnO共混物；里层(离表层10~30 nm处)的主要组成为Cr2O3-ZnO-Zn共混物；钝化膜的成膜过程可能包括镀锌层的溶解、碱性薄层的形成、胶状膜的形成和胶状膜转化成钝化膜4个步骤。

Adopting cathode protection of the zinc materials as an effective protection method, which already applied more and more in many field.
