    Why rusting happens ?

    Rusting is such a common problem that it is quite easily recognizable. Rust (Ferrous Oxide, Fe2O3, and Ferric Oxide, Fe3O4) is an orange colored surface coating, ranging in texture from scaly to powdery. It is loosely bound and the outer layers will usually come off when rubbed by hand or brushed against. It is not a deposit on the surface. Rust is the result of the combination of the iron (Fe) with oxygen (O) in the air, in the presence of moisture. The presence of rust means that some original iron material has been converted to iron oxide and irreversibly lost from the cast iron piece.

    The probability of rust occurring is generally dependent upon two factors:

    1. The degree of protection (usually a protective coating) provided to keep moisture from contact with the metal, and

    2. The degree of moisture present in the air.
