Abstract

The susceptibility of 90/10 Cu-Ni alloy to crevice corrosion induced by Desulfovibrio vulgaris was investigated using a custom-designed crevice structure device under varying media conditions. There was no crevice corrosion in 20 % carbon source (CS) medium inoculated with D. vulgaris, whereas noticeable crevice corrosion occurred in 100 % CS D. vulgaris medium. The uneven distribution of D. vulgaris biofilms between the crevice interior and exterior resulted in localized variations in cathodic species concentration and electrochemical potentials, identified as key factors driving and accelerating crevice corrosion. The deceleration of crevice corrosion in the later stages was attributed to a decline in electrochemical driving force, likely caused by the diminished metabolic activity of D. vulgaris.

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.
