Outline
Electrochemical testing techniques，featuring high sensitivity，in-situ real-time monitoring，and multi-scale analysis，have become a core tool for studying corrosion mechanisms and evaluating protective performance of materials. This paper reviews the classification and recent advances of electrochemical testing methods. The characteristics and applicable conditions of traditional and localized electrochemical techniques are analyzed and compared. The role of multi-technique coupling and artificial intelligence data analysis in testing complex corrosion systems and elucidating mechanisms are discussed. The application of electrochemical techniques from the perspectives of corrosion behavior and mechanism research， protective performance evaluation， and online corrosion monitoring are systematically summarized. Finally， it points out that the development of electrochemical testing techniques lies not only in the popularization of single techniques but also in prioritizing the advancement of multi-technique coupling and high-spatiotemporal-resolution in-situ electrochemical characterization， enabling in-depth analysis from the extraction of intrinsic interfacial reaction parameters to the comprehensive understanding of corrosion mechanisms. On this basis，data-driven approaches and intelligent algorithms are integrated to establish quantitative correlations between electrochemical responses and the service life of materials. Furthermore，integrated and lightweight intelligent monitoring systems enable real-time assessment and lifetime prediction under complex engineering conditions，thereby promoting the transition of corrosion electrochemical testing from laboratory-based mechanistic studies to full-life-cycle safety management of engineering materials.
