| 摘 要： | 通过考察乳酸,酒石酸,柠檬酸和有机酸Y组成的复合络合剂对镀速的影响,确定了合适的复合络合剂,其中复合络合剂由柠檬酸与有机酸Y组成,柠檬酸含量为10g/L,有机酸Y为20g/L.测定了该酸性化学镀镍的镀层的结合力以及孔隙率与耐蚀性,结果表明,该化学镀镍层光亮平整,结合力强,孔隙率分布较窄,耐硝酸点蚀120s,具有优良的耐蚀性能.

| Abstract: | An optimal process of acidic electroless nickel plating was obtained by studying the influences of complexants(lactic acid and organic acid Y,tartaric acid and organic acid Y,citric acid and organic acid Y) on the deposition rate.The complexant in the bath is composed of citric acid(10 g/L) and organic acid Y(20 g/L).The adhesion,corrosion resistance and porosity of the deposits obtained by the process were tested.The tests showed that the acidic electroless nickel deposits are bright,smooth,adhesion and na... |
