Definition - What does Iron Corrosion mean?
Iron corrosion is the destruction of a metallic material that contains the element iron (Fe) due to chemical reactions with oxygen (O2) and water in the surrounding environment.
Corrosionpedia explains Iron Corrosion
Iron corrosion is generally characterized by the formation of rust due to an electrochemical process in the presence of water, oxygen and an electrolytic salt solution. Therefore, the remediation of one or all of these reactant sources can be used to reduce the rate of corrosion in a given metal.
When iron reacts with water and oxygen, iron (II) hydroxide is formed. The latter further reacts with oxygen and water to then form hydrated iron (III) oxide - widely known as rust.
