Fundamentals and critical appraisal of electrochemical techniques for investigating microbial corrosion
Résumé
Electrochemical (EC) techniques are crucial in detecting microbiologically-influence corrosion (MIC) in both laboratory and field settings. This review fundamentally examines the electron transfer mechanisms and microbial interactions with corroding metal surfaces, emphasizing the strengths and inherent limitations of EC in accurately assessing corrosion rates across various scales. The non-destructive and electrical stimulating techniques are discussed, highlighting their applicability for in field conditions. Emerging local techniques are assessed for their potential in laboratory MIC investigations. Despite their limitations, advanced EC methods, integrated with microelectrodes and microscopy, facilitate exploration of MIC phenomena in a multi-evidence approach.
