When present in sufficient concentrations, inorganic and organic chemicals form a broad family of corrosion inhibitors that, in general, impact the whole surface of a corroding metal. More efficient corrosion inhibitors are organic or inorganic compounds with elements from groups V B, VI B, or with amine, alcoholic, or carbonyl functional groups.The inhibitor is absorbed over the whole metal surface, preventing corrosion attack [8].The inhibitors may be divided into two categories: those that produce a protective barrier film on cathodes or anodes as a result of an interaction between the metal and the environment, and those that do not
