Corrosion Inhibition of inconel (600) In Sodium Chloride solution by Sodium sulphate

A potcnliostatic investigation lias been carried out of the corrosion behaviour ofInconel (600) in chloride ions(Cl ) over the temperatures293 to 308 K.The work alsoinvolved the examination of the inhibiting effects of sodium sulphate on the corrosion of the alloy in chloride ions ,Such changes were examined in both the dcacratcd and oxygenated atmospheres .The presence of sodium sulphate in the chloride solution caused a decrease in the corrosion current density and a shift in the corrosion potential towards less negative values . Values of the kinetic parameters , and of (he thermodynamic quantities of inconel corrosion in chloride ion in both deaerated and oxygenated atmospheres in the absence and the presence of sodium sulphate have been determine. The corrosion reaction was generally feasible on thermodynamic grounds .The kinetic results on inconel (600) occurred on surface sites having different energies of activation
