the formation and growth of an aluminium oxide layer
Anodising is the conversion of a metal to a metal oxide on the suface of an item using an electrochemical process. Aluminium is the most commonly anodised metal due to the ease and simplicity of the process coupled with the significant increase in corrosion protection. Not only does the anodising process help maintain aluminium parts, it creates an attractive, low-maintenance and low-cost finish that is able to be dyed to a large range of different colours.
