51316-7357-The Microbiologically Influenced Corrosion (MIC) Resistance Behavior of 2205 Cu-bearing Duplex Stainless Steel in the Presence of Aerobic Marine Pseudomonas Aeruginosa Biofilm

In this study, the MIC resistance behavior of a 2205 Cu-bearing antibacterial duplex stainless steel (2205 Cu-DSS) in the presence of marine corrosive bacteria Pseudomonas aeruginosa was investigated. Electrochemistry evaluation, surface observation, corrosion product analysis were applied.

Recently, more and more reports indicated that microbiologically influenced corrosion (MIC) severely influences the safety of petroleum installations and marine infrastructures. Conventional MIC mitigation methods are physical scrubbing, coatings, and biological or biocide treatments to inhibit the corrosive biofilm. A novel antibacterial 2205-Cu duplex stainless steel (DSS) was developed from the material aspect to mitigate the corrosive marine biofilm by the release of Cu2+ and copper-rich phases on the antibacterial DSS surface. In this study, the MIC resistance behavior of a 2205 Cu-bearing antibacterial duplex stainless steel (2205 Cu-DSS) in the presence of marine corrosive bacteria Pseudomonas aeruginosa was investigated. Electrochemistry evaluation, surface observation, corrosion product analysis were applied. The experimental results demonstrated that 2205 Cu-DSS possessed a better MIC resistance than commercial 2205 DSS in the presence of P. aeruginosa.
