The coating grows from the base aluminium metal by this electrochemical process. The coating is integral to the metal and can not peel or flake. The structure of the coating is many small hexagonal pores, which are filled with a "seal" that hydrolyzes these pores to fill them with inert aluminum oxide which is a hard durable, substance that protects the base metal.
