Effect of chloride and sulfate ions in simulated boiler

The pitting corrosion behavior of 13Cr steel was investigated in simulated boiler waters containing chloride ions (Cl −) and sulfate ions (SO 4 2−) using potentiodynamic and potentiostatic polarization tests in addition to pit morphology analysis.The presence of 100 ppm Cl − in the water caused pitting corrosion of the steel. Pit initiation was inhibited by the addition of 50 ppm or 100
