Description

In this study, the influence of various concentrations of molybdate (MoO42-) on critical pitting temperature (CPT) of duplex stainless steel 2205 (DSS 2205) in 0.1M NaCl solution has been investigated by employing potentiodynamic and potentiostatic CPT measurements methods. No significant increase in CPT was observed in the presence of 0.0001 and 0.001M molybdate. However, addition of 0.01M MoO42- increases 10°C in CPT and pitting corrosion was not observed in solution containing 0.1M molybdate up to 85°C. Potentiostatic CPT measurements showed CPT values of 68 and more than 85°C in 0.01 and 0.1M molybdate concentrations, respectively.
