Do you know what is anodizing?
In general are made with aluminum or aluminum alloy as anode and cathode lead plate is selected, the aluminum and lead plate in the aqueous solution, there are sulfuric acid, oxalic acid, chromic acid, etc., electrolysis, make the surface of the aluminum and lead plate forming an oxide film. The most common of these acids is anodic oxidation using sulfuric acid.
In addition to metals, other substances do anodic oxidation, also known as anodic oxidation.
In the real process, in view of the anodic oxidation of aluminum alloy, is more, can be used in daily life, thought that the characteristics of the process, make produce hard protective layer on the surface of the aluminum, can be used in the production of kitchen utensils and appliances and other daily necessities. But the anodizing effect of casting aluminum is not good, the surface is not bright, but only black. Aluminum alloy profiles need to be better.
