摘要：

The electrochemical impedance technique was applied to study the corrosive and electrochemical activity at the metal/rust interface in connection with the application of protective treatments to rusted steel. The pretreatments assayed were tannic or gallic acid solutions of different concentrations. The impedance diagrams of the treated samples with these solutions were only slightly modified with reference to those obtained with untreated rusted steel. The shape of the low-frequency arcs or tails in the Nyquist diagrams seems to be markedly influenced by diffusion processes in the rust layer and/or by the porous nature of the rusted steel electrode.
