Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. 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, therefore, a matter of highly controlled oxidation the enhancement of a naturally occurring phenomenon. Regardiing aluminum parts after cnc machining process, we usually appy anodizing to obtain a decorative, durable, corrosion-resistant surface.
Quais são os benefícios da anodização colorida?
Os benefícios da anodização colorida estão listados abaixo:
Uma variedade de cores pode ser aplicada durante a anodização da cor. Isso torna o processo adequado para clientes em potencial que consideram a cor como um fator antes de fazer uma compra. Além de ser esteticamente agradável, a anodização da cor não afeta a aparência metálica das peças de alumínio.
Accrual of economic benefits is made possible as a result of the extremely long life span of the anodized products. Maintenance and operating costs can be reduced by a considerable amount.
Anodizing is useful that it provides a perfectly formed oxide layer around the metal. This ensures that its metallic quality is preserved against the destructive process of corrosion。
