【摘要】 利用红外光谱和Ｘ射线光电子能谱对化学镀Ｎｉ－Ｗ－Ｐ合金镀层表面膜进行了研究，结果表明，Ｎｉ－Ｗ－Ｐ合金镀层表面存在一层薄而致密的氧化膜（钝化膜），而镀层内的Ｎｉ、Ｗ、Ｐ则均以零价态形式存在。更多还原

【Abstract】 Surface film of electroless Ni W P coating is investigated by using infrared spectrography and XPS.Its results show thin and compact oxidized film (passivated film) exists on surface of Ni W P coating,while Ni,W and P is present in form of zero valent state.更多还原
