Explain Corrosion.
Corrosion: The process of constant eating (or destruction) up of metals (by the surface) by the surrounding is termed as corrosion. These metals are corroded while exposed to the atmosphere. The metals are usually converted in their oxides. Such oxide covers the surface of the metal that results in the destruction of the metal. Rusting of iron is general illustration of corrosion in that iron makes iron oxide with oxygen of the atmosphere. This iron oxide covers the surface in the form of brownish powder. Thus, the conducting material must be corrosion resistant.
