NACE CORROSION BASICS - CORROSION may be defined as the deterioration of a material (usually a metal) because of a reaction with the environment. Why do metals corrode? Most metals are found in nature as ores. The manufacturing process of converting these ores into metals involves the input of energy. During the CORROSION reaction the energy added in manufacturing is released, and the metal is returned to its oxide state.
