Introduction
Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an
electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the
aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with
the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of
highly controlled oxidation—the enhancement of a naturally occurring phenomenon.
