Abstract
Microbiologically influenced corrosion inhibition represents a promising and eco-friendly technology. As a key component, the role of extracellular polymeric substances and their interaction mechanisms with material surfaces deserve in-depth investigation. Herein, we evaluated the contributions of biofilm components from Tenacibaculum mesophilum D-6 to corrosion inhibition. Results indicated that released polysaccharides (RPSs) played a crucial role in mitigating corrosion. Both pitting and uniform corrosion of X80 pipeline steel were inhibited by RPSs. Weight loss tests indicated that 5 g/L RPSs achieved a corrosion inhibition efficiency of 58.9 %. Further investigations were conducted to elucidate the interaction mechanisms between RPSs and metal surfaces.
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.
