ABSTRACT
Corrosion inhibitors can be defined as chemicals, either inorganic or organic, which, when added in small quantities to a corroding system, significantly reduce the corrosion rate of the metal/alloy concerned. Thus, they provide corroding surfaces with some levels of protection by either forming a film thereon or reacting with the corroding surface to form inert compounds. In most cases, the compounds formed incorporate the ionic species of the metal/alloy in the corroding system as well as species from the inhibitor.
