镀锌层三价铬常温彩色钝化工艺

摘要

Normal temperature corrosion resistance of the color of trivalent chromium passivation can obtain good corrosion resistance, high performance, color and luster is bright beautiful color passivation membrane. On the basis of a large number of experiments, the authors discussed the complexing agent, metal salt, pH, passivation temperature, immersion time and the relationship between the corrosion resistance of passivating film, obtain good passivation processing technology to provide the powerful basis.%常温耐腐蚀的彩色三价铬的钝化,可获得耐蚀性良好、高性能、色泽亮丽的彩色钝化膜.在大量实验基础上,我们讨论了络合剂、金属盐、pH 值、钝化温度、浸泡时间和钝化膜的耐蚀性之间的关系,为我们获得良好的钝化加工技术提供了有力的依据.
