Question
________ is the process of forming a thick layer of oxide of aluminium.
- Galvanization
- Rusting
- Anodizing
- None of the above
Hint:
Anodizing is a process of forming thick layer of oxide of aluminium.
The correct answer is: Anodizing
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell.
