【摘要】 运用ＳＥＭ研究了在含稀土元素的镀液中化学镀Ｎｉ－Ｐ合金时初期沉积过程的形貌，并与普通化学镀Ｎｉ－Ｐ工艺进行了比较。研究表明，添加少量稀土元素能提高镀速，细化镀层晶粒，降低工艺温度，并使镀液稳定性得到提高。更多还原

【Abstract】 Abstract The morphology and structure of RE electroless NiP deposits were studied by SEM and compared with plain NiP coatings.The results showed that a small amount of additive addition could decrease bath temperature,improve bath stability and refine grain size. \=更多还原
