Abstract
Abstract The effect of propargylic alcohol (PA) on the corrosion inhibition of low alloy CrMo steel in sulphuric acid at the open circuit potential E oc was investigated by DC-polarization and AC-impedance spectroscopy measurements, respectively. It was found that the addition of PA induced the positive shift of E oc and the decreasing of cathodic currents. The anomalous Tafel cathodic slopes were explained using a modified adsorption–interaction model. The inhibition process was treated as the substitutional adsorption process. The adsorption of PA was fitted well by means of Flory–Huggins isotherm. The standard free energy of adsorption of PA was calculated (−15 kJ mol −1 ).
