Question

Explain the term anodization with example.

Answer 1

1. This process uses electrolysis to coat metals like copper and aluminium with a thin, strong layer of their oxides.
2. The copper or aluminium item serves as an anode in this process.
3. This oxide layer is helpful in preventing metal corrosion since it is strong and consistent across the surface.
4. Example: For instance, a thin layer of aluminium oxide is formed when aluminium is anodised.
