摘要
在铁片试样上研究以次磷酸钠为还原剂的化学镀Ni—Fe—Ru-P合金镀层的工艺，考察了金属盐浓度对化学镀反应沉积速率的影响。利用优化的工艺配方在经过敏化、活化处理后的纳米碳纤维表面沉积Ni—Fe-Ru-P合金镀层，分别利用EDS、XRD、SEM等手段对镀层的成分、结构、形貌进行了表征，并对其进行了热处理。结果表明，利用化学镀技术可以在纳米碳纤维表面获得连续、均匀的Ni—Fe—Ru—P合金镀层，且镀层为非晶态结构。在350℃以下热处理不会改变镀层的结构，
The process of electroless Ni-Fe-Ru-P alloy plating on iron was investigated by using NaH2PO2 as reducing agent. The effect of the concentration of main salt on deposition rate was studied. Ni-Fe-Ru-P alloy coating was deposited on sensitized and activated carbon nanofibers via electroless plating. The composition, structure and morphology of the alloy coating were characterized by energy-dispersive spectroscopy （EDS）, X-ray diffraction （XRD） and scanning electron microscopy （SEM）, respectively. The structure of the annealed alloy coating was also investigated via heat treatment. The results showed that continuous and uniform alloy coating can be deposited on carbon nanofibers with amorphous structure which is not changed at an increased temperature of 350 ℃, but it begins to crystallize at 400 ℃.
