The corrosion inhibition of mild steel in 1 M HCl solution by some dihydropyridine has been studied using gravimetric, electrochemical impedance spectroscopy, potentiodynamic polarization techniques and quantum chemical study. The results of weight loss and Tafel polarization measurements showed that among the studied compounds, Isradipine has good inhibiting properties for steel corrosion in acidic bath, with 98% inhibition efficiency at optimum concentration 400ppm. The inhibition is of a mixed anodic–cathodic nature. The adsorption behaviour of the investigated compounds is found to obey Langmuir adsorption isotherm. Quantum chemical parameters, were correlated with the experimental results.
