摘要
研究了刷镀镍-磷合金溶液中乳酸、柠檬酸对镍-磷合金沉积速率及其耐蚀性的影响。实验表明:随乳酸的质量浓度增加,沉积速率先增加后降低;随柠檬酸的质量浓度增加,沉积速率降低。当乳酸的质量浓度一定时,柠檬酸为5～20g/L时,刷镀层沉积速率变化不大。同时添加乳酸和柠檬酸两种配位剂,能明显提高刷镀层的沉积速率和耐蚀性能。
The effect of lactic acid(C3H6O3) and citric acid (C6H8O7·H2O) in Ni-P alloy brushing liquid on Ni-P alloy depositing speed and corrosion resistance are investigated. The experiments show that the depositing speed first increases,and then decreases along with the increment of lactic acid mass concentration while the depositing speed decreases with the increment of citric acid mass concentration. With a given lactic acid mass concentration,when citric acid mass concentration is at 5～20 g/L,there is a small c...
