摘要：

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 1 M 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 0 001 M molybdate However addition of 001 M MoO42- Increases 10 degrees C in CFT and pitting corrosion was not observed in solution containing 0 1 M molyb-date up to 85 degrees C Potentiostatic CPT measurements showed CPT values of 68 and more than 85 degrees C in 001 and 0 1 M molybdate concentrations respectively (c) 2010 Elsevier Ltd All rights reserved
