Original Paper


Pitting corrosion resistance of 2205 duplex stainless steel aged at 850 °C was investigated in the hot concentrated seawater (i.e., the simulated low-temperature multi-effect distillation environment) by optical microscopy (OM), scanning electronic microscopy (SEM), and electrochemical measurement techniques. The precipitation of the σ phase leads to sensitization in the specimens during the aging treatment. The degree of sensitization (DOS) presents a maximum value with the change of σ phase content. The pitting corrosion resistance of the specimens degrades markedly in the presence of very weak sensitization. The pitting potential decreases almost linearly with the logarithm of DOS. The pit propagation mainly takes place along the Cr-depleted region around the σ phase. The repassivation ability of the specimens changes insignificantly with the aging time.
