Abstract

VCoNi medium-entropy alloys (MEAs) have been reported to exhibit a high ultimate tensile strength, a good hydrogen embrittlement resistance and an excellent abiotic corrosion resistance. However, the microbiological corrosion of VCoNi MEA is always ignored. Desulfovibrio vulgaris (D. vulgaris) corrosion of the as-cast and homogenized VCoNi MEAs was systematically investigated herein. The results showed the as-cast VCoNi MEA experienced significant microbiological corrosion under the action of D. vulgaris cells. The thermo-mechanical treatments involving cold-rolling and annealing improved the microbiological corrosion resistance of the VCoNi MEA. The results provide a new strategy for the development of novel MEAs with enhanced microbiological corrosion resistance.
