This review describes the recent advances in the basic principles and applications of local electrochemical measurement techniques.The focus of this review is on the application of electrochemical methods, such as scanning vibrating electrode technique(SVET),scanning Kelvin probe(SKP),localized electrochemical impedance spectroscopy(LEIS) and scanning electrochemical microscopy(SECM) in the field of corrosion and protection,both on theories and techniques.The spatial resolution and reliability of local electrochemical measurement techniques greatly increases the utility of these techniques for the characterization of localized corrosion and the electrochemical behavior of single and mixed phase structure.Researches,by using advanced local electrochemical measurement techniques in the areas of localized corrosion and the electrochemical behavior of single and mixed phase structure,are aimed at accumulating corrosion experimental data and accelerating the development of these techniques.
