摘　　要：现有陶瓷基体电热薄膜采用丝网印刷制备工艺,其效率与精度较低,且使用的电阻浆料价格昂贵。采用电铸方法制备出Fe-Ni电热合金薄膜。对所制备的Fe-Ni合金箔电阻率测量分析发现:合金箔电阻率随电铸液Fe浓度及糖精浓度升高而增大,随电铸电流密度增大而呈现先增大后减少的趋势,随电铸液温度及电铸液pH值的升高而减小。To improve the low efficiency, poor accuracy and resistance paste high cost of ceramic-based electrical heating foil by existing preparation technology of screen printing, electroforming technology is applied to prepare Fe-Ni alloy foil. The electrical resistivity of Fe-Ni alloy foil is measured and analyzed, with the results showing that the resistivity increases along with the rise of Feconcentration and saccharin concentration, tends to increase first and decease after with the increase of current density, and decreases as the temperatures of electroforming fluid and pH value rise.
