英文摘要	Microbiologically influenced corrosion (MIC) is becoming a knotty problem for transmission pipelines. Developing MIC mitigation strategies for pipelines is increasingly urgent. In this study, MIC resistance against Pseudomonas aeruginosa of the X65 pipeline steels with (X65Cu) and without (X65) Cu addition was comparatively studied by electrochemical measurements and surface observation. Experimental results demonstrated that the corrosion rate of X65Cu steel was lower than that of X65 steel no matter in sterile or bacteria-containing media. Cu addition is helpful to the formation of the rust layer in the sterile medium. Surface observation showed that X65Cu steel exhibited a better MIC resistance against P. aeruginosa than that of X65 steel. Cu ions released from the X65Cu steel could effectively kill the P. aeruginosa attached on the steel surface, thus evidently decreased the pit depth and diameter.
