Question
Among the following that is not a method to prevent corrosion?
- Electroplating
- Crystallization
- Alloying
- Galvanization
Hint:
Crystallization is not a method to prevent corrosion.
The correct answer is: Crystallization
- The process of coating a metal object with chromium, silver or any other metal by electrolytic deposition to prevent corrosion is called electroplating.
- Alloying is a situation one metal is coated with another metal to reduce reaction with the air.
- Galvanizing is the process of applying a protective zinc coating to steel or iron to prevent rusting.
- Crystallization is not a method to prevent corrosion.
