✦ Synopsis

The anodic d i w d u t i o n of vanadium in 0.5 H,SO, in the potential range of E,,,,, to 2000 mV (SCE) was investigated by DC polarization electrochemical impedance spectroscopy, (EIS). The impedance behavior can be satisfactory described by a series of corrosion reactions where changes in the surface during the various stages of corrosion are emphasized. Study of the effect of temperature on the vanadium at open circuit potential and the value of activation energy support one-electron transfer step as the rate-determining corrosion process.
