The study of the etching of aluminum foil under alternating current

The etching of high purity aluminum foil under alternating current is investigated In the electrolyte, the hydrochloric acid and some corrosion inhibitors, such as sulphuric acid, nitric acid and phosphoric acid, play the very important roles during the etching of aluminum foil. At the same time the frequency the electrolyte temperature, the alternating current density and the etching time greatly affect the specific capacitance of the etched aluminum foil. Adopiting the optimal electrolyte and etching process, we can obtain the etched aluminum foil with high specific capcitance.(12 refs )
