摘要
通过比较,阐述了三价铬钝化相对于六价铬钝化的优势。讨论了各工序(包括镀锌、出光、钝化、水洗和干燥)及杂质离子(包括Zn2+和Fe3+)对钝化膜性能的影响,介绍了工艺控制及杂质离子的消除。
The advantages oftrivalent chromium passivation over hexavalent chromium passivation were expatiated through comparison of the two processes. The effects of individual procedure （including Zn plating, bright dipping, passivating, rinsing and drying） and impurity ions （such as Zn^2＋ and Fe^3＋） on the performance of passivation coating were discussed. The process control and impurity ion removal were introduced.
