Explanation:
Anodizing is a method for changing the surface chemistry of metals and other substrates. It protects against corrosion, enhances aesthetic qualities, resists scratching and is one of the most durable surface finishes available. Anodizing can be done on a range of materials, but today let's look at aluminum.

In the most surrounding -inside or in the open air -aluminium has a very high resistance to corrosion. one reason for this is that aluminium is covered spontaneously by a thin but effective coating of oxide which protects the aluminium from further oxidation
