化学镀光亮Ni－P合金的实践与认识

The Practice and Knowledge of Brightening Electroless Ni-P Alloy

叙述了化学镀光亮Ｎｉ－Ｐ合金镀液在施镀过程中的试验方法．由大量的试验表明．主盐ＮｉＳＯ４·６Ｈ２Ｏ和ＮａＨ０２ＰＯ２·Ｈ２Ｏ补充比例．以重量比为１：１．１～１．２较为合理．

The article demonstrated the method of the plating bath for brighteningelectroless Fi-p Alloy in the process of plating. A lot of experiments showed that the reasonable ratio of the adding main salt NiSO4. 6H2O and NaH2PO2 and NaH2PO2· H2O is from1: 1. 1 to 1: 1. 2 by weight.
