Abstract
The de_adsorption behavior of four inhibitors on N80 steel with and without carbonate film was investigated by polarization and electrochemical impedance spectroscopy (EIS) techniques. It was found that,for different inhibitors,de_adsorption behavior and adsorbability between with and without carbonate film are different.Furthermore,acidic inhibitor and small size molecule inhibitor shows different inhibition behavior.
