摘要	The corrosion inhibition effect of phenanthroline (Phen) and its cobalt complex (CoPhen) on the corrosion of carbon steel in sulphuric acid solutions was studied using potentiodynamic polarization and electrochemical impedance spectroscopy techniques at 20, 30, and 40 A degrees C. Scanning electron microscopy techniques were used to characterize the mild steel surface. The results indicate that the compounds inhibit the corrosion of mild steel in H2SO4 solutions through a predominant physical adsorption following the Langmuir adsorption isotherm. Polarization curves suggest that the complex and ligand are mixed-type inhibitors. The efficiency of the inhibitors is concentration- and temperature-dependent and follows the trend CoPhen > Phen.
