摘 要: 采用電沉積方法， 制備了鐵箔、鐵基合金（Fe-Ni, Fe-Co, Fe-Ni-Co）箔、 鎳箔、 鎳基合金（Ni-Fe）箔，利用掃描電鏡觀察了金屬箔的組織形貌， 直流開路磁場(chǎng)下測(cè)定了電沉積金屬箔的基本磁性能。 實(shí)驗(yàn)表明： 電沉積鐵基合金箔晶粒小于10 μm，電沉積鎳基合金箔晶粒大小在2 μm左右； 電沉積Fe-Ni合金箔是一種性能良好的軟磁材料， 其基本磁性能優(yōu)于傳統(tǒng)熔鑄-軋制坡莫合金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.
