Oxidation corrosion is brought about by the direct attack of oxygen at low or high temperature on metal surfaces in the absence of moisture. Alkali metals (Li, Na, K etc.,) and alkaline earth metals (Mg, Ca, Sn, etc.,) are rapidly oxidized at low temperature. At high temperature, almost all metals (except Ag, Au and Pt) are oxidized. The reactions of oxidation corrosion are as follows. Mechanism: Oxidation takes place at the surface of the metal forming metal ions. M → M2+ + 2e- 2) Oxygen is converted
Corrosion is an important problem which resulting a terrible waste of both resources and money during the application of metallic materials. It also limits the dissolution of environmentally toxic metals from the components [ ]. So corrosion control is important in extending the life of equipment. The first step in corrosion control is identifying type of the corrosion, to evaluate the risk associated with failure in any item. Given a known the type of the corrosion, a strategy of corrosion management
