摘要：

Passivity of corrosion-resistant alloys (CRA) in chloride (Cl-) + hydrogen sulfide (H2S) environments was investigated electrochemically to clarify the role of alloying elements. Fitting potential (V(.)c) was correlated with alloying elements of Ni Cr, and Mo. Ni was shown ineffective in improving pitting resistance in Cl- environments. Passivity in Cl- + H2S environments was discussed based upon Auger electron spectroscopy (AES) analysis, and the roles of each alloying element were clarified.
