Introduction Metals undergo natural destruction that allows a spontaneous deteriorating reaction where they return to their original state from where they are obtained upon contact with the surrounding‚ particularly when reacted to oxygen. Such phenomenon is known as corrosion (Zumdahl‚ 1998). This leads the surface of the materials to rust in due time. Usually
