Review of the application of digital holography in corrosion studies

Purpose The purpose of this paper is to review the application of digital holography in studies of the corrosion of metallic materials. Design/methodology/approach Digital holography is used for in situ observation of the dynamic processes at the electrode | electrolyte interface and on the electrode surface during the corrosion dissolution of metallic materials. Findings Digital holography is an effect method to in situ observe the corrosion processes, and it can provide a direct experimental foundation for studying the corrosion mechanism. Originality/value Even though there are several challenges, digital holography will play a significant role in studying corrosion processes.
