【摘要】 镓锡合金沉积于铝阳极表面 ,形成活化点 ,是含镓、锡铝合金阳极活化的根本原因。溶液中的卤素离子在氧化膜上的吸附及在其中的扩散也促进了铝电极的阳极溶解。合金元素及溶液中的阴离子通过改变铝电极表面的零电荷电位 ,影响着合金元素在铝电极表面的沉积的难易程度 ,从而影响着铝合金阳极的活化性能更多还原

【Abstract】 The major reason for Al-anode’s activation is that Ga and Sn can deposit on the aluminum surface and form activated points. At the same time, the adsorption and penetration of anions such as Cl -1 ,Br -1 ,I -1 in oxide film can promote the anodic dissolution of Al-anode. Alloy elements in the Al-anode and anions in the solution can change the potential of zero charge of Al-anode. This effects the deposition of alloy elements, thus influenceson on the activation of Al alloy anode.更多还原
