From Wikipedia, the free encyclopedia
Anodising, or anodizing, is a technique used to modify the surface of a metal. It may provide greater corrosion resistance, create a different surface topography, and change the crystal structure close to the metal surface. The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process.
Anodisation is frequently used to protect aluminum and titanium from abrasion and corrosion and to allow it to be dyed in a wide range of colors.
