This article systematically reviews and discusses the application of advanced surface characterization techniques for surface corrosion monitoring in metals at the micro- and nanoscale. It also presents the in situ, real-time nanoscale topography evolution method that enables measurement of time-dependent local dissolution rate. The study highlights the importance of correlative advanced techniques in identifying nanoscale corrosion mechanisms and improving corrosion predictive models.
The nanoscale quantification of the electrochemical behavior in metals is critical to understanding the microstructure-corrosion relationship and subsequently controlling it. In this article, the application of advanced surface characterization techniques-atomic force microscopy (AFM), vertical scanning interferometry (VSI), digital holography microscopy (DHM), and other quantitative phase microscopy (QPM) techniques-for surface corrosion monitoring in metals at the micro- and nanoscale are systematically reviewed and discussed in detail. Interestingly in situ, real-time nanoscale topography evolution that enables measurement of time-dependent local dissolution rate as often tracked from numerical construction of QPM is also presented. This study demonstrates the considerable attributes of correlative advanced techniques for identifying nanoscale corrosion mechanisms, enabling the informed development of next-generation inhibition technologies, and improving corrosion predictive models.
