中文摘要:
      应用电化学方法研究了Ni-Fe-W合金的电沉积机理,并对Ni-Fe-W合金镀层的微观形貌和组成成分进行了表征。循环伏安测试表明,Ni-Fe-W合金电沉积是不可逆电极过程,且WO42-浓度的变化不改变电沉积机理;计时电流法研究表明,Ni-Fe-W合金在铜电极上的电结晶过程符合三维瞬时成核的生长机理;SEM和EDS结果表明,Ni-Fe-W合金镀层由纳米级的小颗粒组成,合金的组成为Ni 58.76%,Fe 32.72%,W 8.52%(原子数分数,后同)。
英文摘要:
      The electrodeposition mechanism of nickel-iron-tungsten alloy were studied by the methods of electrochemistry, and the micromorphology and composition of nickel-iron-tungsten alloy were characterized.Cyclic voltammogram indicated that the electrodeposition of nickel-iron-tungsten alloy wasirreversible growth process,and the electrocrystal-lization mechanism didn't change with the variety of the concentration of WO42-.Chronoamperometric results indicated that the electrodeposition of nickel-iron-tungsten alloy at copperelectrode belonged to a three-dimensionalinstantaneous nucleationmech-anism. SEM images of electrodeposit showed that the nickel-iron-tungsten alloy was made of lots of crystalline grain which was several tens nanometers, and the atom composition was 58.76%Ni,32.72%Fe,8.52%W.
