- •
LPR and EIS showed that P. aeruginosa reduced the corrosion resistance of 2205 DSS.
- •
The largest pit depth on 2205 DSS was 4.9 μm after 14 days incubation in sterile medium.
- •
The largest pit depth on 2205 DSS was 14 μm after 14 days incubation with P. aeruginosa.
- •
The accelerated pitting was due to the formation of CrO3 and CrN by P. aeruginosa.
