The electrochemical oscillatory phenomenon induced by the adsorption and desorption of organic corrosion inhibitor in the active potential region of HCl solution on the surface of Fe electrode was investigated and the influence of corrosion inhibitor concentration, electrode potential and solution agitation on the oscillation behavior was studied. The active potential region of Fe electrode in HCl medium also obtained regular current oscillatory wave, but the oscillatory behavior under the same conditions is weaker than that of H2SO4. With the increase of corrosion inhibitor concentration, the period of oscillation wave becomes longer and the oscillation weakens ; From the cathode to the anode, the current oscillation waveform is different, the cycle also increased; stirring had no significant effect on the current oscillation .At the same time reported a new phenomenon of constant current potential oscillation in the corrosion inhibition system
