摘要
提出了一种低温化学镀镍工艺，可在７０℃下进行（常规工艺操作温度为８５～９５℃），槽液稳定，沉积达率不小于１０μｍ／ｈ，使用寿命达５个周期以上，并得到磷的质量分数为０．０２～０．０５的Ｎｉ－Ｐ合金镀层。Ｈ２ＰＯ２－和Ｎｉ２＋影响沉积速率的反应级数分别为０．３和０．３４，Ｈ２ＰＯ２－的平均利用效率为０．７６。
The electroless nickel process of low temperature (LTEN ) has been studied. It can be plat ed at 70℃(the operating temperature of convertional process is 85-95℃). The bath is stable.Thedeposition rate is more than 10 μm/h. The service life is more than five turns.The Ni-P alloy coatingscontaining quality fraction of 0.02-0.05 phosphorus have been obtained.The reaction order forH2PO2 was.0.3 and that for Ni2+ was 0. 34.The average utilization efficiency of H2PO2 in the bath is0.76.
