Microbiological Induced Corrosion (MIC) occurs due to the interaction of the activities and metabolites of the microorganisms with metal materials, which affects the cathodic and anodic processes of corrosion reactions. This phenomenon accounts for approximately 20% of marine corrosion hazards, rendering it a major technical problem for the marine industry. The study of microbial corrosion in marine environments is of great significance to promote the development of the Chinese marine industry. Microbial corrosion of metal materials includes both comprehensive corrosion and local corrosion, with local corrosion being more harmful. Among various forms of local corrosion, pitting corrosion is considered the most harmful.
