0 present participle of anodize
1 to cover a metal with a layer of oxide by using an electric current
The color that results on a titanium ring depends on the thickness of the oxide coating, which is determined by the anodizing voltage.
Anodizing the foil creates pores in the foil a micrometer deep and 60 nanometers wide.
The source material can be equipped before structuring with a high-quality surface finish, such as painting, anodizing and marking.
The process is called "anodizing" because the part to be treated forms the anode electrode of an electrical circuit.
Although anodizing only has moderate wear resistance, the deeper pores can better retain a lubricating film than a smooth surface would.
Painting, anodizing or plating metals are good ways to prevent their corrosion.
The anodizing current varies with the area of aluminium being anodized, and typically ranges from 30 to 300 amperes/meter (2.8 to 28 ampere/ft).
Sulfuric acid soon became and remains the most common anodizing electrolyte.
