Description

The anodic oxide structure originates from the aluminium substrate and is composed entirely of aluminium oxide. This aluminium oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminium substrate, so it cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as colouring and sealing.
Anodising is accomplished by immersing the aluminium into an acid electrolyte solution and passing a current through the aluminium. A cathode is mounted to the inside of the anodising tank; the aluminium acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminium atoms at the surface of the part being anodised. Anodising is, therefore, a matter of highly controlled oxidation - the enhancement of a naturally occurring phenomenon.
