摘　　要：通过化学镀法在铝箔表面施镀微量的锌元素,对镀锌后的阳极铝箔腐蚀扩面的过程及机理进行研究。结果表明,化学镀锌后,铝箔在腐蚀过程中其表面形成Zn-Al微电池效应,促进了铝箔的电化学腐蚀,改善了隧道孔形貌,使铝箔的隧道孔分散均匀,孔径减小,且密度明显增大,进而增大了铝箔的比电容。Zinc was deposited on the surface of aluminum foil by electroless plating,and the corrosion and expansion process and mechanism of the aluminum foil were investigated.The results showed that after chemical galvanizing,Zn-Al micro battery was formed on the surface of aluminum foil during the corrosion process.This promoted the electrochemical corrosion of aluminum foil,and improved the morphology of the tunnel holes,made the holes dispersed evenly,decrease the aperture and increase the density,thereby enlarge the specific capacitance of the aluminum foil.
