Atomic-Scale Processes in Cu Corrosion and Corrosion Inhibition

摘要

In our belief, the examples given here have impressively demonstrated the rapid increase in mechanistic understanding, on an atomic scale, of metal-corrosion processes brought about by modern in situ techniques, most notably by in situ scanning-probe microscopy. It has be- come possible to identify and structur- ally characterize the individual reaction sites for metal dissolution, providing new insight not the microscopic mecha- nisms underlying the macroscopic cor- rosion behavior. This way, the decisive role of surface defects, which had been postulated already by Stranski as active sites for the corrosion reaction, could be confirmed.
