Aluminum Anodizing and Its Advantages

Anodizing is not like electroplating and other organic coatings, it is unique to aluminum. This has greatly expanded the application of aluminum products and uses after it has developed in the early 1930-ies, where the metal or other non koristi.Anodne finish is now available from aluminum finishing work shops around the world and is quite inexpensive.

Anodizing will convert the aluminum oxide surface. Although, of course, a form of aluminum oxide on the surface, it will be very thin film. It offers a thicker oxide layer thickness several times if potrebno.Krutost the alumina coating challenges that diamond. Because of this anodizing improves abrasion resistance. It can also significantly alter and improve the appearance of aluminum. By the use of color and special procedures, finisher can make aluminum look like stainless steel, tin, copper, or brushed bronze. The process will improve corrosion resistance, particularly when exposure to the metal surface in humid, industrial and marine atmospheres. Electrical insulating property of anodic end of its application when dielectric properties important for electrical components. This type of aluminum is easy to clean and resists heat to high temperatures, where the metal itself melts.

can be defined as the anodizing process of electrochemical conversion, and do not apply premaz.Površine metal is converted into aluminum oxide as a result of the reaction occurs at the anode in an acidic solution. Oxide formation generally gets inward, towards the source of fresh metala.Prvi formed oxide will remain in contact with the anodizing solution all through the process cycle, the last formed oxide is metal sučelje.Premaz will be almost 30-50 percent thicker than the original metal it replaces.

Structure of most coatings is predominantly porous. There will be a very slight non-porous barrier film at the interface. Management process begins with the quality of the metal, its precleaning and shelves, and finally ends with unracking, possible "clean" and technical pregledu.Finišer job shop or captive department generally has the least control over an important requirement for good anodizing the metal quality. Type of mill product, alloys, worth, temper and so on has a significant impact on the appearance, oxide coating property and functional properties such as wear and corrosion resistance of the end product.

finisher must know about the metal being treated. Some process changes should be, and in particular quality standards will be difficult to achieve, except the alloy is anodized. It can be formed in the range of chemical solutions, although only a few are uporabu.Prednost industrial anodizing of aluminum's potential color anodizing colors. These color seeps into the microscopic pores of anodized layer and colors. This layer is then sealed and the color appears as part of the metal itself. It can be used to great artistic effect, the aluminum parts with striking flavors colors of your motor bike, or more locally, the telescope.
