摘要
在酸性硫酸盐．氯化物一柠檬酸盐复合镀液体系中电沉积Fe-Ni．Mo合金箔，探讨了电沉积的工艺条件及镀液组成对合金箔组成的影响规律，确定复合镀液组成为：硫酸镍120～180g／L，氯化镍40g／L，硫酸亚铁30-80gm，Mo粉10～30g／L，硼酸30g／L，柠檬酸钠100-150g／L，抗坏血酸15∥L，糖精3edL，表面活性剂1g／L，聚乙二醇2g／L，pH值为2．5．通过SEM、XRD和EDS的分析表明：合金箔表面平整光滑，结构致密，表面无明显孔洞和裂纹，随Mo含量增大，合金箔平整性下降，表面粗糙度也增大：合金箔为FeNi置换固溶体和面心立方晶体结构，钼是以微粒相进入FeNi固溶体；合金箔的织构主要为（111）、（200）晶面，合金箔介于晶态与非晶态之间的纳米晶合金．
Fe-Ni-Mo Alloy foils were electrodeposited from acidic sulfate-citrate- chloride composite electrolyte. This paper discusses the effects of the electrolyte compositions and other technique conditions on the components of the alloy foil, uses SEM, XRD and EDS to characterize the surface morphology, microstructures and chemical component of the alloy foil, and testified that the Fe-Ni-Mo alloy foils are of nanocrystalline structure and present strongly preferred orientation of （ 11 l） plane and （200） plane. The alloy foils, FCC FeNi solid solution with Mo particle, have uniform and dense texture, and smooth surfaces on which no pitting or cracking can be detected.
