How to Anodized Work

Metallic material or article after surface anodized, corrosion resistance, hardness, wear resistance, insulation, heat resistance, etc. are greatly improved. Anodized metal material up to deal with implementation is aluminum. Anodized aluminum is generally carried out in an acidic electrolyte, containing aluminum as an anode. In the electrolysis process, the role of oxygen anions and aluminum oxide film produced. This film is formed early enough fine, although some resistance, but the negative oxygen ions in the electrolyte can still reach the surface continues to form an aluminum oxide film. As the film thickness increases, resistance also becomes large, so that the electrolytic current becomes small. At this time, the outer oxide film in contact with the electrolyte chemical dissolution. When the speed of the aluminum oxide surface gradually and chemical dissolution rate of the balance, the maximum thickness of the oxide film can be achieved under the electrolysis parameters. Aluminum porous anodic oxide film outer layer, and is easily adsorbed dye colored substances, which can be dyed to improve its decorative property. After the oxide film and then hot water, high temperature steam or nickel salt blocking treatment can further improve the corrosion resistance and abrasion resistance. In addition to aluminum, the use of surface anodized metal alloys as well as magnesium, copper and copper alloys, zinc and zinc alloys, titanium, steel, cadmium, tantalum, zirconium, etc. industry.
