아노다이징은 금속 표면을 장식용으로 변환하는 전기화학적 공정입니다., 튼튼한, 내식성, 양극 산화 마감. 알루미늄은 아노다이징에 이상적입니다., 다른 비철금속에도 불구하고, 마그네슘 및 티타늄과 같은, 또한 양극 처리될 수 있습니다.
The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as coloring and sealing.
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, 그러므로, a matter of highly controlled oxidation - the enhancement of a naturally occurring phenomenon.
