What happens to metal when it rusts?
Iron, as well as iron alloys, rusts because of a chemical reaction known as oxidation.
When iron is exposed to moisture or oxygen, oxidation occurs.
During this chemical reaction, iron is converted into iron oxide.
The iron oxide typically has a reddish, flaky appearance that becomes progressively worse over time..
