Corrosion inhibition of carbon steel in chloride solutions by blends of calcium gluconate and sodium benzoate

Inhibition efficiency of calcium gluconate, alone and in blends with sodium benzoate, on the corrosion of carbon steel in chloride solutions has been assessed by potentiodynamic polarization measurements and mass loss detection in the temperature range from 25 to 70 Celsius degrees. Sodium benzoate efficient in hindering the general corrosion in chloride solutions can induce pitting of carbon steel. Along with decreasing the general corrosion calcium gluconate, an ecologically acceptable compound , eliminated the susceptibility to pitting formation. The inhibition of the anodic reaction by gluconate and benzoate, and the slowing down the cathodic reaction in solutions of calcium gluconate was confirmed.
