【Abstract】 A Fe-36%Ni soft magnetic alloy thin film was prepared by electroplating.The relationships among the molar ratio of Fe²⁺/Ni²⁺,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.更多还原
