Abstract
Corrosion is defined as the deterioration of a metal by a chemical or electrochemical reaction with its environment. This natural phenomenon causes substantial financial losses in various sectors and requires extensive efforts to limit its impact [1]. The three main reasons for the importance of corrosion are: economics, safety, and conservation. The economic item including the reduction of material losses resulting from the wasting away or sudden failure of piping, tanks, metal components of machines, ships, hulls, marine etc. Safety is a critical consideration in the design of equipment especially for nuclear power plants and for disposal of nuclear wastes [2]. The conservation item, applied primarily to metal resources, the world’s supply of which is limited, and the wastage of which includes corresponding losses of energy and water resources accompanying the production and fabrication of metal structures.
