Pitting and galvanic corrosion of 2205 DSS with σ phase were investigated in the presence of . Pitting corrosion was accelerated by σ phase, and further promoted by . The σ phase changed the distribution of pitting sites from being concentrated on phase boundaries and α phase in the solution treated coupons to being around σ phase in the biotic medium. The galvanic corrosion between α and γ phases was enhanced by the bacterium, and σ phase led to anodic dissolution of γ phase instead of α phase in DSS with solution treatment.

铜绿假单胞菌存在下σ相对2205双相不锈钢局部腐蚀的影响

研究了存在 σ 相的 2205 DSS 的点蚀和电偶腐蚀。 σ 相加速点蚀， 进一步促进点蚀。 σ相改变了点蚀位点的分布，从集中在溶液处理的试样中的相边界和α相到生物介质中的σ相周围。细菌增强了α相和γ相之间的电偶腐蚀，并且固溶处理的DSS中σ相导致γ相而不是α相阳极溶解。
