Anodising is a surface treatment which is used to give the aluminium product additional protection against corrosion, decorative surfaces with resistant colour and gloss, electrical insulating surfaces or foundations for gluing or painting. Anodising is an electro-chemical process that strengthens the natural oxide shift.
Anodising is a process in which the normal thin layer of oxide on the surface of aluminium is artificially thickened to give it added protection from corrosion. It is done by making aluminium the anode in an electrolysis cell in which dilute sulphuric is electrolysed.
A process, which produces a hard, abrasion-resistant, protective oxide film on the surface of aluminium or its oxides. This film is able to absorb and retain certain dyes, making it ideal for 'colour anodising' or 'aluprinting'.
The production of an oxide layer on aluminium alloys. The process is electrolytic, a typical electrolyte being sulphuric acid. Treatment at room temperature produces thin, decorative layers with some corrosion protection. Treatment at 0oC produces hard, thicker layers (up to 100ยต) with wear resistance. They can be post sealed to give improved corrosion resistance.
Anodising, or anodizing, is a technique used to coat the surface of a metal with an oxide layer. It may be used to increase corrosion resistance, increase wear resistance, allow dyeing or prepare the surface for other processes and coatings including paint. Anodization changes the microscopic texture of the surface and can change the crystal structure of the metal near the surface.
