Anodic oxidation, photocatalytic oxidation of a metal or aluminum alloy. The process by which layers of air oxide film are produced on aluminum (anodized) metal (anodized) in a lithium battery electrolyte and a special process standard due to the effect of additional current. Anodizing, if not very pointed, is hydrochloric acid anodizing.

In order to get rid of the surface strength of aluminum profiles, wear resistance and other shortcomings, expand the scope of application, increase the use of life, metal surface treatment technology has become an indispensable link in the application of aluminum profiles, and anodic treatment technology is widely used at the present stage and the most successful.

According to the current, the cathode, dissolved radon gas; On anodic oxidation, dissolved oxygen (containing molecular oxygen, molecular oxygen, and positively ionized oxygen) is generally expressed as O2 in the reaction. The anodized aluminum is oxidized by the dissolved oxygen in the air to produce an anhydrous film of iron oxide.
