摘要
运用回归正交设计对影响硫酸盐溶液电解成型Ｎｉ－Ｆｅ合金箔质量的主要工艺因素进行了实验，建立了合金箔成分、电流效率和槽电压与工艺参数之间的二次回归方程，分析了各因素的影响规律，并在直径 ３５０ ｍｍ的辊式旋转阴极机列上进行了连续电解成型 Ｎｉ－２０Ｆｅ合金箔的实验验证，结果表明：制得的范材为 γ－Ｎｉ固溶体，成分稳定、厚度均匀、表面光滑，抗拉强度和延伸率分别为１０８０ ＭＰａ和０．５％．经热处理后抗拉强度和延伸率分别为３４５ ＭＰａ和１３％，电阻率为０．２６１μΩ·ｍ，Ｃｕｒｉｅ温度为 ８５３ Ｋ（５８０℃）；最大导磁率为 ２．１４８×１０－２ Ｈ／ｍ，磁感应强度为 １．１６９ Ｔ，矫顽力为 １１．８５７ Ａ／ｍ．
The technology of the electrolytic deposited Ni-Fe alloy foils from sulfate solution was researched using orthogonal regression design. Quadratic regression equations of the composition of al- loy foils, current efficiency and bath voltage varied with bath composition, pH and current density have been established. The effects of operating parameters on Ni-Fe alloy foils were extensively discussed. The results obtained are verified by continuous electrolytic deposition of Ni-20Fe alloy foil on the rotating cathode drum, and show that Ni-20Fe alloy foil has γ-Ni solid solution structure, stable composition, uniform thickness, smooth and clean appearance and good mechanical and electromagnetic performance.
