Abstract In this paper, corrosion inhibition of 1,4-butynediol in epoxy coatings was studied by means of electrochemical method and IR spectrum. Experimental results showed that the inhibitor obviously increases the corrosion- resistance of epoxy coatings. When the amount of 1,4-butynediol corrosion inhibitor is less than 0.5mass% in the coating, the impedance of coating increases with addition of the corrosion inhibitor. Through the impedance data which is fitted by ZSimpwin software and analysis of the IR spectrum, we suggest that the incomplete corrosion inhibitor film with double bonds is formed between coating and substrate. The inhibitor mechanism of the corrosion inhibitor film was also discussed by means of electrochemical method.
