Corrosion and rusting are two chemical processes, which result in disintegration of materials.
-->Corrosion is the layer-by-layer spoiling or degrading of any metallic surface through such agents as oxygen, water vapour, hydrogen sulfide and other possible pollutants.
-->Rusting is merely a specific case of corrosion where the metal surface concerned is iron and the red-brown flakes of Fe2O3.nH2O that form are what is called rust.

(1) Corrosion : Corrosion is a process in which metals are eaten up gradually by the action of air , moisture or a chemical on their surface .
Corrosion is caused by the oxidation of metals by the oxygen of air.
(2)Rusting : rusting of iron metal is a most common form of corrosion .
when an iron object is left in the ampere for a considerable time it gets covered with the with the Red Brown flasky substance called rust . This is called rusting of iron .
Simply, corrosion of iron is called rusting.
