Abstract
Corrosion is a naturally occurring phenomenon generally defined as deterioration of metal surface caused by the reaction with the surrounding environmental conditions. Corrosion can cause disastrous damage to metal and alloy structures causing economic consequences in terms of repair, replacement, product losses, safety and environmental pollution. It is necessary to devote more attention to metallic corrosion nowadays than earlier due to more corrosive environment as aresult of increasing pollution of air and water, increased use of metals within all field of technology (Uhlig and Revie (1985).The corrosion costs in the most of the countries are in the range of 2-4% of the gross national product. So it is imperative that economically , useful measures should be taken to minimize Corrosion (Sastri (1998).The total annual cost of corrosion in the U.S is approximately 276 billion dollars and increasing every year (Mercier and Barthés-Labrousse (2009). Due to these harmful effects, corrosion is an undesirable phenomenon that ought to be prevented. There are several ways of preventing corrosion. This is in addition to the rates at which it can propagate with a view of improving the lifetime of metallic and alloy materials. The use of inhibitors for the control of corrosion of metals and alloys which are in contact with aggressive environment, is one among the acceptable practices used to reduce corrosion.
