    Corrosion is the gradual destruction of material, usually metals, by chemical reaction with its environment. This means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting, the formation of iron oxides , is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal. Corrosion can also occur in materials other than metals, such as ceramics or polymers. Although in this context, the term degradation is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases.

    It is a process in which material without any external protection gets depleted slowly with reaction with the environment...and they loose all their properties...
