Iron surface, Auger spectra

Figure 6. XPS C Is (left) and 0 Is (right) spectra of the interfacial substrate surface of epoxy-amine coating on bare steel following cathodic polarization testing (solid curves). Also shown is an approximate curve resolution for each spectrum components of the C Is spectrum are, from left, alkane, ether, and carbonate principal components of the 0 Is spectrum are, from left, iron oxide, carbonate, ether, ad adsorbed water (29.) or sodium Auger ( ).
