Question

How is an iron gate prevented from rusting?

Answer 1

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.............plz mark as brainliest

Answer 2

Answer:We can use a process called galvanization to prevent rusting of iron gate.

Explanation:To prevent  iron materials coming in contact with oxygen and water vapour present in air, a layer of another metal like chromium or zinc are coated on that iron material to prevent rusting. this process of coating other metal on iron materials to prevent rusting is called galvanization.
