“…With the increase of dissolved oxygen concentration in seawater, the content of oxygen diffusing to metal surface and the speed of oxygen cathode depolarization also increase, which leads to the acceleration of corrosion rate. These results are different from those studied by using NaCl as corrosion solution only [28,29].…”

Surface characterization and corrosion behavior of 90/10 copper-nickel alloy in seawater from Xiamen bay at 30 °C for 56 days were investigated in this study. The results indicated that the corrosion product layer was mainly a mixture of CuO, Cu2O, and Cu(OH)2, with a transition to CuCl, CuCl2, and Cu2(OH)3Cl during the corrosion process. However, as corrosion proceeds, the resistance of the product film was reduced due to its heterogeneous and fairly porous structures, which led to local corrosion of the alloy. The corrosion potentials (Ecorr) increase while corrosion current densities (Icorr) decrease with time because of the formation of protective oxide film.

Sulfate-reducing bacteria (SRB) were found to be capable of tolerating a certain amount of oxygen (O), but how they affect oxygen reduction reaction (ORR) has not been clear. The present work investigated the impact of SRB on ORR in 3.5 wt% sodium chloride solution with the cyclic voltammetry method. The addition of SRB culture solution hampered both the reduction of O to superoxide (O) and hydrogen peroxide (HO) to water (HO), and the influence of SRB metabolites was much larger than that of bacterial cells. Sulfide and extracellular polymeric substances (EPS), typical inorganic and organic metabolic products, had great impact on ORR. Sulfide played an important role in the decrease of cathodic current for HO reduction due to its hydrolysis and chemical reaction activity with HO. EPS were sticky, easy to adsorb on the electrode surface and abundant in functional groups, which hindered the transformation of O into O and favored the reduction of HO to HO.
