Steel painted samples were submitted to immersion tests monitored by open circuit potential and electrochemical impedance. The behaviour of calcium-exchanged silica was compared with chromate and red iron oxide. The electrochemical measurements were complemented by water vapour permeability, Auger electron spectroscopy and thermally stimulated currents. The results suggested a film forming mechanism for calcium exchanged silica paintings. In total immersion conditions, they had better performance than the iron oxide, closely approaching the chromate. (C) 2001 Elsevier Science Ltd. All rights reserved.
