Abstract

Passive oxide films formed on metal surfaces can be broken by Veaddition of aggressive ions like chloride while these films reinforced or prevented from being broken down by the addition of inhibitors. This can be examined by monitoring the changes in the reflectivity of the surface. The nature of the passive films formed has been studied by optical reflection in NaCI-NaOH and NaCl-sodium benzoate media for a mild steel electrode. Likewise metal ions are used to reinforce corrosion inhibition or as inhibitors. Such cations are thought of as being deposited as monolayers at potentials more positive than the reversible Nernst potentials. The monolayer formationof lead on a mild steel surface from solutions containmg ~ b + +ha s also been examined by monitoring the reflectance changes
