Question

How galivaisation help to protect iron object from rusting? ​

Answer 1

Answer:

Galvanising is a method of rust prevention. The iron or steel object is coated in a thin layer of zinc. This stops oxygen and water reaching the metal underneath - but the zinc also acts as a sacrificial metal . Zinc is more reactive than iron, so it oxidises in preference to the iron object.

Answer 2

1. It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron.
2. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
