USES OF ANODIZING

• Generally, aluminum alloy is easy to oxidize, although the oxide layer has a certain passivation effect, but the result of long-term exposure, the oxide layer will peel off and lose its protective effect, so anodizing is to use its easy oxidation characteristics, by electrochemical method to control the generation of the oxide layer, to prevent further oxidation of aluminum, while increasing the mechanical properties of its surface, another purpose is to Through different chemical reactions to produce a variety of colors to improve the appearance, widely used in aircraft skin, military weapons, copier paper roller, building aluminum curtain, aluminum doors and Windows.

• Anodizing provides a variety of surface modification effects, such as coating a thick and porous surface to make the dye more easily absorbed, or a thin transparent layer to increase the ability to reflect light.

• Anodizing is also used to avoid sharp angles or rough edges caused by screw rubbing, and is also used as the dielectric of the electrolyte container. The anode layer is most commonly used to protect aluminum alloys. So the metal or alloy is used as the anode, and the oxide film is formed on its surface by electrolysis.

The anode layer is most commonly used to protect aluminum alloys. So the metal or alloy is used as the anode, and the oxide film is formed on its surface by electrolysis. 

•The metal oxide film changes the surface state and performance, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, protecting the metal surface.
