摘要
由于六价铬的高毒性,镀锌层三价铬钝化工艺是一种替代六价铬钝化工艺的良好选择。其中三价铬蓝白钝化是一种优良的防护-装饰性膜层。详细阐述了影响蓝白色钝化膜性能的主要因素。经过不断的试验,研究出了一种组分简洁的镀锌层三价铬蓝白色钝化液,性能稳定,外观和耐蚀性优良。
Hexavalent chromium is a high toxicity material and may cause environment pollution. And trivalent chromium passivation film is an excellent protective and decorative film on zinc coating. A new kind of trivalent chromium bright blue passivation process with simple components and stable bath and with excellent performance of film was developed. The influence factors for the performance of trivalent chromium bright blue passivation film are introduced.
