We can prevent corrosion by Galvanisation ,sacrificial protection and barrior protection.
Galvanisation is the process of coating zinc over iron so as to protect it from rusting.
Sacrificial protection is a method in which the exposed iron surface is protected by connecting it to some reactive metal like magnesium,zinc,aluminium etc
Barrior protection is the method of painting so as to prevent the contact between the air and the metal.
