Corrosion is a principle challenge to industries as it causes structural weakness, reduced bond strength, ductility, and shear capacity of metal . According to international studies, the reports indicates that overall cost of corrosion that happens interms of loss of metal as a result of corrosion is at least four to five percent of the gross national product (GNP), and out of this 20 to 25 % loss can be saved using efficient and correct corrosion prevention technology . Mitigation of corrosion is more practical than its complete elimination . Metal can be protected against corrosion to occur by various ways like use of non-corrosive metals, provide corrosion free environment, using principles of galvanic protection, electroplating and barrier corrosion resistant coating.
