| 摘 要： | 部分高合金钢磷化效果不佳,甚至难以磷化.通过正交试验,对30CNi3A合金钢黑色锰系磷化工艺进行了优化研究,分析了磷化过程中总酸、酸比、Fe2+浓度、表调时间、磷化时间等因素对磷化膜耐腐蚀性能和膜重的影响.结果表明,适当的总酸、酸比、磷化时间以及降低Fe2+浓度有利于提高磷化膜的耐腐蚀性能.为提高磷化膜的耐腐蚀性能,应尽量使磷化膜晶粒细小均匀,增加膜重,提高磷化膜中锰的含量,降低磷化膜中铁的含量.

| Abstract: | A series of orthogonal tests were carried out to investigate the technology for manganese sys-tem phosphating of 30CrNi3 alloy steel at elevated temperatures. The effects of total acidity, ratio of total acidity to free acidity, ferrous ion concentration, activation time and phosphating time on the mass per unit area and corrosion resistance of the phosphating film were analyzed. Results show that by properly controlling the total acidity, the ratio of total acidity to free acidity, and phos-phating time an... |
