ABSTRACT
Metals and their alloys are continuously exposed to acid in the industrial process. Successful enterprises cannot tolerate major corrosion failures and considerable efforts are made in corrosion control at the design stage and in the operational phase. The literature dealing with corrosion of aluminum and possibility of its prevention using eco-friendly inhibitors is examined. The inhibitor effectively secures the metal against corrosion attack. Most inhibitors are organic compounds containing oxygen, nitrogen, and sulfur. These compounds are adsorbed onto the metallic surface blocking the active corrosion sites. This paper discusses the efficiencies of nontoxic eco-friendly inhibitors to reduce the corrosion rate of aluminum.
