H_2PO_2^-的氧化方式与化学镀Ni-P合金历程

The Oxidized-manner of H_2PO_2^- and Course of Ni-P Alloy Electroless Plating

硫酸镍 次亚磷酸钠体系中的化学镀反应 ,是一个在多相体系中进行的复杂物理 化学过程 ,因此 ,存在多种关于它的理论或看法。综合目前较为流行的几种理论认为 ,各种机理理论存在的最大差别在于H2 PO 2被氧化方式上的差异。文中还结合自己的研究结果 ,认为化学沉积Ni -P合金的机理是一个“氢化物

The electroless plating reaction in NiSO 4-NaHPO 2 system is a complex physical-chemical process in amultiphase system. Therefore, there are many theories and opinions on it. The paper deems that the most difference in these theories lies on H 2PO 2 oxidized manner.Otherwise,a 'hydrid-electrochemistry allied mechanism' in chemical sediment Ni-P alloy process is suggested in the paper by combining some studying results.
