SEARCH Articles Figures Tables A schematic view of replacement of native surface films on active metals by new ones in solutions. It should be noted that in reality the borders between the layers which comprise the surface films are not distinctive, and their microstructure is mosaiclike. This, and the subsequent figures, are attempts to emphasize the fact that the composition and structure of the surface films change as a function of their distance from the active metal.
