摘　　要：通过研究二次腐蚀液中不同浓度的添加剂对铝箔隧道孔形貌及其性能的影响,发现随着添加剂浓度的提高,腐蚀箔表面孔径快速减小,内部孔径逐渐增大,呈现出"大肚子"的特点,同时铝箔表面腐蚀明显减小,蚀孔孔长逐渐增加,折弯随之下降。By studying the effects of different concentrations of additives on the morphology and properties of aluminum foil tunnel,it was found that with the increase of additive concentration,the pore diameter of the corrosion foil surface decreased rapidly,and internal diameter increased gradually,it presents the characteristics of the"big belly".At the same time,the surface corrosion of aluminum foil is obviously decreased,and the elongation of the hole is increasing,and the bending is decreased.
