摘　　要：采用变频腐蚀工艺以及正交实验法,制备了铝电解电容器用低压铝箔,研究了腐蚀电源频率对所制低压铝箔腐蚀形貌及性能的影响。结果表明:腐蚀孔径随着电源频率的升高而变小,腐蚀电压随着频率升高而降低;频率25Hz为最佳工艺条件,所得腐蚀样品耐压值为83.2V,比容达16.07×10-6F/cm2。By AC frequency etching process and orthogonal experiment,the low voltage aluminum electrolytic capacitor foil was prepared.The effect of etching frequency on the corrosion image and property of prepared low voltage aluminum foil were studied.The results show that the etching aperture increases and the etching voltage decreases as the frequency increases.Frequency of 25 Hz is the optimum condition.The specific capacitance reaches 16.07×10-6 F/cm2 and withstand voltage is 83.2 V.
