摘　　要：采用电沉积法制备Fe-36%Ni软磁合金薄膜,通过正交实验方法研究了Fe2+/Ni2+摩尔比、镀液pH值、电流密度、镀液温度与合金中铁含量的关系,用极差法分析了各工艺参数对Fe-Ni合金薄膜成分影响的显著性,并确定了最佳工艺条件。优化验证实验结果表明,所得合金薄膜光亮、致密、外观平整,合金薄膜中Fe含量为64.99%(质量分数),Ni含量为35.01%(质量分数),其饱和磁通密度(Bs)0.84T,剩余磁通密度(Br)0.27T,矫顽力(Hc)65A/m。A Fe-36 %Ni soft magnetic alloy thin film was prepared by electroplating. The relationships among the molar ratio of Fe^2＋/Ni^2＋, current density, pH and the temperature of the Fe-Ni alloy-containing bath were studied by orthogonal experiments, the extreme difference analysis was used to distinguish the influencing degree of factors discussed in this paper, and the optimum technique of Fe-36 %Ni alloy electroplating was determined. The test results under optimum conditions showed that the thin film was bright, fine, uniform with better performance, and the chemical composition of the deposit was consisted of Fe 64.99wt% and Ni 35.01wt%. The saturation flux density, residual flux density and coercivity for the electroplated Fe-36%Ni alloy samples were respectively 0.84T, 0.27T and 65A/m.
