Anodising is the process of creating an aluminum oxide coating by making an aluminum part anodic while suspended in an electrolyte. The electrolyte most commonly used is 15% by weight sulfuric acid. The process takes anywhere from thirty minutes to one hour, and the thickness ranges from depending on voltage, time, temperature, metal grade.Its actually very similar to what a chef does in a high end restaurant The aluminum oxide coating that is produced is porous by nature and has the ability to adsorb dye or exhibit an excellent anchor profile for paint. It can be also be sealed if these properties are non-desirable.
Sulfuric acid anodizing produces an oxide coating on aluminum alloys that increases corrosion resistance and may also be used as a base for paint coatings. Other uses are for limited abrasion resistance, electrical insulation and for decorative purposes. Conventional sulfuric acid anodizing is most useful making aluminum parts more attractive and more corrosion resistant. The natural appearance of the aluminum oxide film is near transparent, and left as-is, it is known as clear anodising. This is the most economical form of anodizing.
