| 摘 要： | 以锌、钙、镍、锰为主要成膜物质,硝酸盐为促进剂,有机酸为稳定剂,研制了一种中高温拉拔型磷化液。该磷化液不含亚硝酸根,磷化过程中无需添加调整剂、沉渣少、性能稳定,其磷化膜特点在于耐磨、耐压,具有可塑性,主要用于金属标准件加工的前处理。通过钙离子浓度对磷化膜影响的研究,考察了总酸度、游离酸度、磷化时间以及磷化温度对膜重的影响,并得出了较佳的磷化工艺。

| Abstract: | A phosphating solution was developed for middling and high temperature drawing,which used Zn-Ca-Ni-Mn as main materials of phosphating film,nitrate as accelerant and organic acid as stabilization agent.It had no nitrite and regulative agent,less sedimentary residue and more stable capability.The effects of Ca2 concentration on total acidity,dissociative acidity,time and tempareture of phosphating processing on phosphating film were studied.Optimal phosphating parameters were obtained. |
