摘要：

The corrosion behaviors of 2205, 2205-Cu, and 2205-Cu-Ce duplex stainless steels (DSSs) were studied under static load in the presence of sulfate-reducing bacteria (SRB). The results demonstrated that the addition of Cu and Ce effectively enhanced the resistance of 2205 DSS to SRB-assisted cracking, and 2205Cu-Ce DSS exhibited the best corrosion resistance and mechanical properties. The Synergistic addition of Cu and Ce not only inhibited the formation of SRB biofilm but also enhanced the hydrogen-induced cracking resistance of DSSs due to the hydrogen trapping by Cu-rich precipitates.
