Pitting corrosion inhibition of 304 stainless
steel (SS) in groundwater with a ternary inhibitor mixture (phosphonic acid + bivalent cation + various surfactants) was studied with different environmental variables such as temperature, pH, dissolved oxygen and chloride ions. Critical pitting potential and corrosion potential were calculated for these test media using electrochemical techniques. Under the tested condition, the localized corrosion resistance of 304 SS was determined and the results are discussed.
