摘要：

The electrochemical behaviour of mechanically polished molybdenum electrodes in different acid and alkali solutions was investigated using open-circuit potential and impedance measurements. The effect of the concentration of acid (HCI) and alkali (NaOH) on the elctrochemical behaviour of the molybdenum electrodes was also studied. The various kinetic parameteres, i. e. capacitance, resistance and potential, controlling the mechanism of oxide film growth were monitored as functions of time.
