研究了施加稳恒磁场(H=0~0.7 T)对电沉积铁-镍合金箔的影响。测定了垂直电流方向,不同强度磁场下的电流效率、合金组成及合金箔的磁性能,并用扫描电镜和X射线衍射观察合金箔的微观形貌和结构,分析讨论了稳恒磁场对这些性能的影响规律。结果表明:与不施加磁场相比,施加垂直磁场后合金箔表面更均匀、细致、平整;合金箔铁含量提高约14%;合金箔(111)晶面取向程度增强,磁性能有所改善;但铁-镍合金电镀的电流效率呈先增加后下降的趋势。
The effect of applying constant magnetic field (H = 0 ~ 0.7 T) on the electrodeposited iron-nickel alloy foil was studied. The current efficiency, the composition of the alloy and the magnetic properties of the alloyed foil in the direction of vertical current, magnetic field with different intensity were measured. The microstructure and morphology of the alloyed foil were observed by scanning electron microscopy and X-ray diffraction. The effects of the steady magnetic field on these properties Affect the law. The results show that the surface of the alloy foil is more uniform, fine and smooth when the vertical magnetic field is applied compared with no magnetic field. The content of iron in the alloy foil is increased by about 14%. The degree of orientation of the alloy foil (111) plane is enhanced and the magnetic properties are improved. However, the current efficiency of iron-nickel alloy plating first increases and then decreases.
