摘 要：<正>This work intends to investigate the inhibition behaviour of 2-butine 1,4diol and potassium sodium tartrate and their synergistic effects on 3003 aluminium alloy corrosion in 0.5% NaCl solution.Experiments were carried out by electrochemical impedance spectroscopy（EIS）and Tafel polarization method in a three-electrode cell. It was concluded that the inhibition efficiencies increased with an increase in the concentrations of inhibitors. For 2-butinel,4diol and tartrate salt,the optimum in the inhibition efficiency,at room temperature and neutral pH,was observed for concentrations close to 10-3 mol/L and 1.5×10-3mol/L,respectively.The electrochemical results illustrated that 2-butinel,4diol and tartrate salt,have significant synergistic inhibition effects on corrosion of 3003 aluminium alloy in 0.5% NaCl solution.The optimum ratio of concentrations for tartrate to alcohol was 2:1.
