Alum anodizing
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

Anodizing serves multiple purposes: it dramatically improves corrosion resistance, enhances surface hardness, provides electrical insulation, and allows for permanent coloring. The anodized layer also serves as an excellent base for adhesive bonding and improves paint adhesion when needed.
Aluminum alloys are anodized to increase corrosion resistance and to allow dyeing (coloring),improved lubrication, or improved adhesion. However, anodizing does not increase the strength of the aluminium object. The anodic layer is insulative.When exposed to air at room temperature, or any other gas containing oxygen, pure aluminium self-passivates by forming a surface layer of amorphous aluminium oxide 2 to 3 nm thick, which provides very effective protection against corrosion
