Analysis of polarization curves and impedance spectra has shown that the surface chemistry of galvanized steels plays an important role in determining their corrosion behavior. Zn-Ni samples that were untreated or had been treated in a 10 mM Ce(NO 3 ) 3 solution had the lowest corrosion rates in 0.5 N NaCl. The efficiency of the surface modification process was the highest for electrogalvanized steel. Surface analysis showed that the protective layers on Zn-Ni and electrogalvanized steel contained mainly cerium oxides/hydroxides, while the layer on hot-dipped steel consisted mainly of zinc hydroxide.
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.
