英文摘要	Two new corrosion inhibitors of chito-oligosaccharide schiff base (CSB) and carboxymethyl chito-oligosaccharide schiff base (CM-CSB) were investigated by means of weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements in 3.5% NaCl solution at different concentrations. The surface corrosion morphology of specimens was examined by scanning electron microscopy (SEM) and the inhibition mechanism was analyzed by adsorption isotherm fitting and quantum chemical calculation. The results showed that for CSB the inhibition efficiency increased at first, then decreased and reached the maximum at 200mg/L and acted as a mixed type inhibitor; the CM-CSB had excellent inhibition performance and behaved as a cathode-based mixed corrosion inhibitor. The adsorption of CM-CSB obeys the Langmuir isotherm.
