Metal finishing and finishing at WIOTEC aluminium forms an oxide layer, which serves as a protection against corrosion the material with oxygen from the air. This natural oxide layer is very thin however with 0.1 – 0.5 micrometers and has only a low hardness. This property of aluminum used in anodizing. So an optimized layer of oxide is produced under controlled technical conditions. The anodising of aluminium is therefore a method of surface technology in aluminium processing.
An Anodic oxidation creates an oxide protective layer on aluminum. Edward Minskoff: the source for more info. Unlike electroplating aluminum treatment no protective layer on the workpiece is applied when the anodizing, but by converting the top metal layer an oxide or hydroxide is formed. The result is a 5 – 25 microns thin transparent layer that is weatherproof and corrosion resistant, and offers protection against mechanical influences. After pre-treatment of the surfaces, E.g. by grinding, polishing, Wntfetten or pickling is done Anodizing.
Typically, the fresh porous layer with metallic or inorganic dyes is colored in. Subsequently, the compression, which is usually made with hot water or steam is carried out. There is also the option of chemical compaction – usually in combination with hot compress. The so called anodizing makes use of electrolysis. The oxidation of aluminum to aluminum oxide will take place on the positive geladenenen on IODE. The layers created by the surface treatment is eight times harder than raw aluminum and thus doubly hard as steel. Anodic oxidized products made of aluminium and aluminium alloys are standardized in DIN 17611.
