Abstract It is demonstrated, by a series of marker experiments, in which layers of nonporous anodic oxide were tagged by incorporating radioactive material in them, that nonporous anodic oxide grows at, or close to, the oxide-electrolyte interface; it is concluded that the aluminum ion is the mobile species. Similar experiments with a porous oxide may also be interpreted in terms of formation of the oxide at the oxide-electrolyte interface, but in this case the interface is at the bottom of pores filled with electrolyte.
