Currently, with the gradual depletion of onshore resources, more efforts are being devoted to both scientific and resource exploitation of the ocean and the deep sea. Compared with the onshore environment, marine habitats are complex and characterized by high hydrostatic pressure, high salinity, and high marine population. The ocean is a unique aquatic environment, and it has a large population of microorganisms. There is a need to exploit the ocean for new energy sources. The significant challenges of exploiting oil, gas, and minerals have forced the people to innovate and develop advanced exploration tools. Al alloys are attractive for use in marine environments due to their low densities, high strengths, good plasticity, excellent electrical and thermal conductivities, and excellent corrosion resistance. The high chloride concentrations and microorganisms in the ocean have a significant effect on the corrosion resistance of many metallic materials. In this work, the corrosion behavior of 5754 Al alloy in seawater containing B.subtilis was investigated. The corrosion rate was analyzed by the weight loss method. The morphologies of the corrosion products and the corrosion profiles were observed by SEM and white light interferometer, respectively. The corrosion products were analyzed by energy dispersive spectroscopy and XRD. Finally, the corrosion mechanism of the Al alloy was studied using electrochemical impedance spectroscopy. The results show that the corrosion rate of the Al alloy in the seawater with B.subtilis was 12.5 mg/(dm2·d), which was only 1/6 times that in the seawater without the bacteria. A protective film comprising of CaMg(CO3)2 was gradually formed on the surface of the alloy in the presence of the bacteria. The bacteria promoted the formation of the CaMg(CO3)2 film, which protected the alloy from the seawater, and consequently, inhibited the pitting corrosion of the Al alloy in the marine environment.
