What is deposited on iron in the process of Galvanization?
zinc
Galvanization Process Explained
Galvanization is a protective process applied to iron or steel to prevent rusting.
It involves coating the base metal with another metal that provides corrosion resistance.
Metal Used in Galvanization
The metal deposited on iron during galvanization is zinc.
This coating is typically applied using methods like hot-dipping the iron into molten zinc.
Function of Zinc Coating
The zinc layer serves two main purposes:
- It acts as a physical barrier, preventing atmospheric moisture and oxygen from reaching the iron.
- It provides sacrificial protection, meaning the zinc corrodes instead of the iron, even if the coating is scratched.
