Sažetak
The effect of propargylic alcohol (PA) on the corrosion inhibition of low alloy Cr-Mo steel in sulphuric acid on the open circuit potential Eoc was investigated by DC-polarisation and AC- impedance spectroscopy measurements, respectively. It was found that the addition of PA induced the positive shift of Eoc and the decreasing of cathodic currents. The anomalous Tafel cathodic slopes were explained using a modified adorption- interaction model. The inhibition process was treated as the substantional 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).
