Pennington: Electrochemical Society Inc., v. 99, n. 26, p. 183-+, 2000.http://hdl.handle.net/11449/31178The electrochemical behavior of metallic chromium in aqueous solutions containing chloride ions at different pH was studied by means of open-circuit potential vs. time measurements, cyclic voltammetry and electrochemical impedance spectroscopy. The composition of the surface oxides was analyzed by XPS. For solutions with pH<3 the formation of a passive layer occurs via a dissolution/precipitation process while for pH>3 the mechanism changes. XPS analysis revealed that Cr2O3 basically constitutes the passive layer.183-+engTrabalho apresentado em eventoWOS:000086691900019Acesso aberto
