| 摘 要： | 为了在电镀锌层表面获得色彩鲜艳、耐蚀性能突出的钝化膜层,研究了电镀锌层低温高耐蚀性三价铬彩色钝化工艺。探讨了络合剂、金属盐、pH值、钝化温度和浸渍时间与钝化膜耐蚀性的关系,得出了最佳工艺规范。在最佳工艺下得到的钝化膜呈均匀、光亮的彩虹色,且耐蚀性能优良;与电镀锌层相比,钝化膜表面呈光滑的凹凸不平状态,这有利于提高膜层的耐蚀性。

| Abstract: | In order to get colourful passivation film with excellent corrosion resistance,the Cr3+ iridescent passivation technology with fine corrosion resistance at low temperature on electrogalvanizing was studied.The corrosion resistance dependences on complexing agent,metal salt,pH,passivation temperature,and dip time were discussed,and the best technological procedure was obtained.The passivation film we got is uniform,shinning with iridescence.And its corrosion resistance is excellent.Compared with electrogalvanizing,the surface of passivation film is smooth and uneven which is in favor of improving the corrosion resistance of passivation film. |
