Abstract
The growth characteristics of sulfate-reducing bacteria (SRB) in crevice and their impact on corrosion were investigated. The results demonstrate that SRB growth can be categorized into three stages. The crevice blocks the diffusion of nutrients, and SRB acquire electrons from the stainless steel matrix to fulfill metabolic requirements, resulting in the formation of a bio-cathode that promotes preferential vertical development of pits.
