in detail :

The gradual eating up of metals by action of air, moisture or a chemical reaction (such as an acid) on their surface is called corrosion. The most commonly seen example of corrosion of metals is rusting of iron i.e the formation of a brown flaky substance on iron objects on exposure to moist air. ✌✌
