The use of digital image correlation for optical monitoring of corrosion processes occurring in ametallic sample is here proposed. The formation and reduction of corrosion products (oxides) over thesurface of an old copper coin immersed in an electrolytic basic mixture is analyzed through a standardelectrochemical characterization and, simultaneously, registered by means of a simple opticalexperimental setup which corresponding sequential images are registered, stored and digitallyprocessed utilizing a digital image correlation method. This method may be helpful for controllingelectrochemical reduction of corrosion products processes, and could be also applied in antique objectscleaning and restoration.
