摘要:With novel mixed aliphatic imidazoline guanidinium as corrosion inhibitor, static weight-loss method and electrochemical polarization curve method were utilized to investigate the corrosion inhibition performance of the compound inhibitor on Q235 steel in 5% HCl solution, and scanning electron microscopy (SEM) was used to observe the corrosion morphology of the metal surface. The experiment results of static weight-loss method showed that the corrosion inhibition rate of carbon steel was 98.39% under the experimental conditions of concentration of 10 mg/L, corrosion time of 18 h, and temperature of 60°C; the results of electrochemical experiments indicated that the corrosion inhibitor was of a kind of adsorption membrane inhibitor dominantly inhibiting anode inhibition.
