Corrosion is the gradual destruction of the metal surface on account of air and moisture.
Two ways of preventing corrosion are galvanisation and coatings.
Galvanisation is coating of thin layer of zinc on the metal which is about to corrode as zinc being highly reactive does not react with air and moisture. Coating is the paint applied on the metal surface.
