摘　　要：对低磷化学镀镍的影响因素进行了初步研究。选择常用的乳酸/丙酸镀液为低磷化学镀镍的研究体系,通过单因素法进行测试。最后的试验结果表明,在其它条件不变的情况下,随着镍磷摩尔浓度比的增大,镀层硬度逐渐上升,而镀速逐渐下降;在其它条件不变的情况下,随着丙酸浓度的增加,平均镀速有所上升,而硬度先上升,达到一个最大值后开始下降。可见,乳酸与丙酸的体系中不同的镍磷摩尔浓度比及乳酸与丙酸摩尔浓度比对镀层的性质有很大影响。The influence factor on low-phosphorous elelctroless nickel plating is studied. The system of lactic-propionic is selected as object and is tested by single factor analysis method. The result of experiment shows that the hardness will increase and the plating rate will decrease with the rising of concentration ratio of nickel sulfate and hypophosphite. Moreover, the average rate can rise and the hardness will reach the maximum along with the increasing concentration of propionic acid. The concentration ratio of nickel sulfate and sodium hypophosphorus has great effect on coating. So does the concentration ratio of lactic-propionic acid.
