    Heterogeneous corrosion behaviors of copper in seawater containing SRB was studied by wire beam electrode method combined with EIS, SEM, and XPS. Results show that charge transfer process, micromorphology, and surface composition, on cathodic area are different with that on anodic area when SRB with high metabolic activity are present.

    Three Schiff bases were synthesized by simple condensation reaction. The synthesized Schiff bases show good inhibition efficiencies for the corrosion of low-carbon steel in 1 M hydrochloric acid solution. SEM-EDX, FTIR, UV-visible, and XRD results proved that the mechanism of corrosion inhibition is occurring mainly through adsorption process.

  3. Interactions of Desulfovibrio desulfuricans biofilm with 2205 duplex stainless steel – the role of microstructure

    The paper presents the results on SRB-induced corrosion of 2205 duplex stainless steel (DSS) in as-received and thermally aged conditions. Electrochemical techniques were applied to monitor bacterial attachment to the steel surface and to determine the effect of bacteria on the passivity and corrosion resistance of 2205 DSS. Results demonstrated that MIC behavior was strongly affected by the microstructure and phase composition of the steel.

  4. Nano-sized zeolite particles as inhibitor carrier in plasma electrolytic oxide layers on AZ31

    The incorporation of a small amount of nano-sized inhibitor-loaded zeolite particles leads to a significant improvement of the corrosion resistance. The study shows that the inhibitor-loaded particles can be incorporated directly during plasmaelectrolytic oxidation in a one-step-process. The risk of pitting corrosion decreases in comparison with inhibitor free anodized layers.

  5. Corrosion properties of low carbon steel prepared by submerged friction stir processing

    The microstructure, electrochemical corrosion, and salt fog corrosion properties of SFSP low carbon steel were investigated. The results indicated that phase transformation and dynamic recrystallization occurred during SFSP and finally resulted in a dual phase fine grain microstructure. SFSP samples exhibited better resistance against electrochemical corrosion and salt fog corrosion than BM samples.
