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.
