摘要
使用丙酸-乳酸体系化学镀低磷Ni-P合金,研究了镀液中镍与磷的浓度比、乳酸、丙酸、pH对镀速和磷含量的影响,并得到了最佳低磷化学镀Ni-P合金工艺。实验结果表明,提高硫酸镍与次磷酸钠的质量浓度比和pH,降低乳酸和丙酸的质量浓度,有利于得到低磷化学镀Ni-P合金层。
The lactic-propionic mixture was employed for the investigation of the low-phosphorous Ni-P alloy electroless plating technics. The effects of various factors, such as concentration ratio of NiSO4·6H2O with NaH2PO2·H2O, lactic acid, propionic acid and pH value, on the deposition rate and phosphorus content of the coatings, were investigated. Accordingly, the optimum parameters for low-phosphorous Ni-P alloy electroless plating were obtained. The research indicates that the low-phosphorous coating can be obtained when increasing concentration ratio of NiSO4·6H2O with NaH2PO2·H2O and pH value and decreasing the concentrations of lactic acid and propionic acid.
