Open publisher page 3 citations

Abstract

The influence of SO42- on the pitting corrosion behavior of 316 stainless steel has been studied by measuring the relationship of corrosion current and temperature in 0.5% Cl- solutions with different concentrations of SO42- at constant applied potentials. The results showed that with the increase of SO42- concentration, the passivation current increased and the open circuit potential decreased; When the concentration of SO42- was less (more) than 0.42%, the critical pitting temperature was lower (higher) than that without SO42-. The inhibition and acceleration effects of SO42- on the pitting corrosion were discussed by analyzing the mechanism of the ion-competitive adsorption.
