Abstract
Microbiologically influenced corrosion (MIC) refers to the deterioration of metal surfaces as a result of the formation of microbial biofilms and metabolic activities at the biofilm/metal interface. Conventional macroscopic electrochemical techniques provide limited spatial resolution to investigate MIC which often occurs at localized environment within micro-/nanoscopic levels. Localized electrochemical techniques have received increasing attention in MIC research as a potential strategy to solve this challenge. This paper provides a focused review of localized electrochemical techniques employed in MIC studies, including their fundamentals and applications. Furthermore, their advantages and challenges as well as topics to be investigated in future are discussed.
