$\implies$Two methods to prevent rusting of iron are:-

• Alloying: Corrosion of some metals can be prevented by alloying them with other metals. For example, iron rusts easily but when it is alloyed with nickle, chromium, and carbon, it forms stainless steel which is resistant to corrosion.
• Electroplating: Corrosion of certain metals can be prevented by depositing a thin protective layer of another metal on them by electroplating. For example, a layer of chromium metal is deposited on steel used for making vehicles. Cans used for packing preserved food stuffs like juices are made of steel coated with tin.
