Electrochemical measurements (steady-state current-voltage curves and AC impedance) were coupled with analytical techniques (reflection-adsorption spectroscopy at grazing incidence and XPS) to investigate the inhibition of corrosion of a carbon steel by a mixture of a zinc salt and a phosphonic acid. From the polarization curves and impedance measurements it was shown that the electrochemical reactions...
Lead-tin alloys were prepared with increasing tin content up to 2.5 wt.% Sn. These alloys were passivated in de-aerated sodium tetraborate solution (pH = 9.1) at 0 V versus saturated sulfate electrode. The aim of this X-ray photoelectronspectroscopy (XPS) study was to elucidate the relationship between the alloying tin content and the electronic conductivity of the passive layers. It was found...
