Galvanisation: Protecting Iron from Rusting
Galvanisation is a process used to protect iron or steel from rusting (corrosion).
It involves coating the iron or steel surface with a thin layer of another metal. This layer acts as a barrier, preventing the corrosive elements (like oxygen and moisture) from reaching the iron.
Key Metal Used in Galvanisation
The specific metal used in the galvanisation process to coat iron is Zinc metal only. Zinc provides both a physical barrier and acts as a sacrificial anode, meaning it corrodes preferentially to protect the underlying iron.
Conclusion
Therefore, galvanisation protects iron from rusting by coating it with a thin layer of Zinc metal only.
