Question

8. Why is it necessary to anodize aluminium
to make corrosion resistant
Ans

Answer 1

Explanation:

Aluminium protects itself against corrosion upon exposure to air by forming a layer of aluminium oxide. If this layer is made more uniform, it protects the aluminium underneath more effectively. Thus, this is done by a process called anodizing to make it corrosion resistant.

Answer 2

Answer:

The main reason for anodising is to protect the aluminium. Thanks to the process, corrosion resistance increases and the material retains its appearance for longer. Anodising creates a hard, wear-resistant layer that properly protects the underlying aluminium.
