摘 要: 采用电沉积方法， 制备了铁箔、铁基合金（Fe-Ni, Fe-Co, Fe-Ni-Co）箔、 镍箔、 镍基合金（Ni-Fe）箔，利用扫描电镜观察了金属箔的组织形貌， 直流开路磁场下测定了电沉积金属箔的基本磁性能。 实验表明： 电沉积铁基合金箔晶粒小于10 μm，电沉积镍基合金箔晶粒大小在2 μm左右； 电沉积Fe-Ni合金箔是一种性能良好的软磁材料， 其基本磁性能优于传统熔铸-轧制坡莫合金1J79。

Abstract: An alternative to conventional processes for the preparation of soft magnetic metal foils of Fe, Fe-Ni, Fe-Co and Fe-Ni-Co, electrodepositing, was described. The microstructure and magnetic properties of the foils were observed. Crystal size of the iron based alloy foil is less than 10μm, while the crystal size of the nickel based alloy foil is about 2μm. Results show that the electrodeposited Fe-Ni foil has better magnetic properties than conventional milled Permalloy 1J79 foil.
