Abstract
The respective roles of IOB and SRB in mixed microbial corrosion of carbon steel pipelines were investigated by surface analysis and electrochemical measurements. The results indicate that in initial corrosion stage the extracellular polymeric substances (EPS) of SRBs can hinder the adhesion of IOB and inhibit corrosion nodulation formation. As SRB:IOB increases from 0:22500 cells/mL to 22500:22500 cells/mL, the size and number of corrosion nodulations decrease by two orders of magnitude. In latter corrosion stage, the SRBs become the dominant microbes, accelerating the propagation of corrosion nodulations in mixed microbial system due to low dissolved oxygen (DO).
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
