Abstract:

The major reason of Al anode activation is that Ga can plate out on the aluminum surface and form activated points. The Al-Sn, Al - Ga binary alloys can't be activat6d in alkaline medium. During the dissolution of the Al - Sn - Ga ternary anode, Sn and Ga dissolove solution aions as ions. After Sn ions deposit on the surface of Al anode, Ga ions will underpotentially deposit on Sn. The higher activation of the polycomponent alloy anode is caused by much more new activated points being continually formed. The activation mechanism for the polycomponent Al-alloy anode in alkaline medium is abided by the" dissolution-deposition".
