Corrosion inhidition of Inconel (600)‎ in sodium chloride solution by sodium sulphate

Abstract EN

A potcntiostatic investigation lias been carried out of the corrosion behaviour of Inconel (600) in chloride ions(Cl') over the temperatures293 to 308 K.The work also involved 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 deacraled 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 the 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.
