Abstract:We present the corrosion of an iron film in brine solution (0.1 NaCl) as measured by liquid TEM.Dissolution of the iron film and nucleation of the corrosion products is captured by imaging. It shows that the nucleation initiates at the metal surface, with preferential growth along the metal grain boundaries. The corrosion product that forms is characterised in-situ as hematite by electron diffraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
