Which means cathode in an electrolytic solution with high chemical stability materials such as lead, stainless steel, aluminum and the like. Anodized aluminum principle is essentially the principle of electrolysis of water. When the current through the cathode and emit hydrogen; at the anode, the precipitation of oxygen is not only the state of the oxygen molecule, including atomic oxygen (O) and oxygen ions, usually in reaction to molecular oxygen expressed. As the aluminum anode is deposited on the oxide oxygen, anhydrous aluminum oxide film formed, not all of the generated oxygen and aluminum effect, part of the gaseous form of precipitation. 2. Select anodized aluminum plate oxide electrolytic solution: a precondition is that the growth of the anodic oxide film, the electrolyte membrane due to the oxidation of dissolution. But this is not to say the same anodized oxide film can be generated in all the presence or dissolution of the oxide electrolyte film properties. 3, the type of anodic oxidation of aluminum plate: anodized by current form is divided into: direct current anodizing, AC anodizing, pulse current anodic oxidation. Divided by the electrolyte: sulfuric acid, oxalic acid, chromic acid, mixed acid and sulfosalicylic acids naturally colored anodic oxide as the main solution. Divided by temper film: general anodized film, the hard film (thick film), ceramic film, bright decorative layer, the barrier effect of the semiconductor layer and the like. 4, anodized aluminum plate oxide film structure, properties: anodized film consists of two layers, the outer layer of thick porous grew up in a dense inner layer having dielectric properties, the latter known as the barrier layer (also called the active layer). It was observed with an electron microscope study, the aspect of the film surface exhibits almost all the surface of the tubular hole and perpendicular to the metal, which penetrate the outer membrane and the metal oxide film until a barrier layer interface. In each porosity of the spindle is surrounded by a dense alumina honeycomb hexagonal body, called the cell, and the entire film is composed of an infinite number of such cell. The barrier layer is composed of alumina and anhydrous, thin and dense, with high hardness and prevent action current through. Barrier thickness from about 0.03-0.05μm, from 0.5% to 2.0% of the total after the film. Porous outer oxide film mainly and a small amount of amorphous alumina and hydrated alumina composition, also contains an electrolyte cation. When the electrolyte is sulfuric acid, the sulfate content of the film under normal circumstances it is 13% -17%. Most of the excellent characteristics of the oxide film is made of a porous outer layer thickness and porosity of the decision of sleep, they are closely related to the anodic oxidation conditions.
