The corrosion inhibition performance of HbbImet for Q235 steel was tested by weight loss method, polarization curve, electrical impedance spectroscopy(EIS) in 0.5mol/L HCl solution, and the corrosion inhibition mechanism of the corrosion inhibition effect for Q235 steel was also discussed. The results showed that the inhibition efficiency increased with the increasing of HbbImet concentration at the same temperature,while decreased as the increasing of temperature with the same HbbImet concentration.The inhibition efficiency of HbbImet can up to 92.23% when the concentration of HbbImet is 120mg/L at 25℃, as well as showed a good corrosion inhibition effect. The apparent activation energy of corrosion reaction was significantly increased by the addition of HbbImet, which indicated that the process of corrosion reaction was effectively inhibited, and it was a mix-type inhibitor which had great restraint action on cathodic hydrogen evolution. 查看全文查看/发表评论下载PDF阅读器 相关附件：附件1版权转让声明书修改说明 -->
