Electrochemical Investigations on the Corrosion Behavior of 904L Stainless Steel in LiBr Solutions

Abstract The pitting corrosion susceptibility of 904L stainless steel in aerated LiBr solutions was investigated. influence various experimental variables, including electrolyte concentrations, pH, scan rate, temperatures, and constant potential has been studied using electrochemical measurements, such as cyclic potentiodynamic polarization, potentiostatic techniques, impedance spectroscopy (EIS). surface morphology examined by scanning electron microscope (SEM). rate uniform toward increases with an increase concentrations temperature. Increasing the pH solution decreases both corrosion. An enhances corrosion, but suppresses EIS diagrams displayed a depressed semicircles center under real axis. Bode plots support result that resistance alloy increasing Br − anion concentration. observations suggest this one time may actually be overlap two-time constants.
