-Anodizing is the process of electrochemically
controlling, accelerating and enhancing
oxidation of an aluminum substrate.
- Oxidation naturally
results from the exposure of a metal substrate to oxygen.During
oxidation, the outside layer of metal is converted to a porous layer of metal and oxygen (an oxide film).This natural oxide film offers minimal protection for the aluminum substrate.
The anodizing process produces an oxide film that is uniform, hard and protects the rest of the aluminum substrate from
