Passivity of corrosion-resistant alloys in environments containing chloride and hydrogen sulfide
- Nippon Steel Corp., Futtsu, Chiba (Japan). Pipe and Tube Steel Research Labs.
Passivity of corrosion-resistance alloys (CRA) in chloride (Cl{sup {minus}}) + hydrogen sulfide (H{sub 2}S) environments was investigated electrochemically to clarify the role of alloying elements. Pitting potential (V{prime}c) was correlated with alloying elements of Ni, Cr, and Mo. Ni was shown ineffective in improving pitting resistance in Cl{sup {minus}} environments. Passivity in Cl{sup {minus}} + H{sub 2}S environments was discussed based upon Auger electron spectroscopy (AES) analysis, and the roles of each alloying element were clarified.
