Abstract
The potentiodynamic polarization curves, quantum chemical calculation and molecular dynamics simulation methods are used to study the inhibition effects of Salen ligand regarding the corrosion of carbon steel (A105) in salty and acidic solutions of 3.5% NaCl and 1.0 M HCl respectively. The results show that the values of inhibition efficiency in 3.5% NaCl and 1.0 M HCl solutions are higher than 96% and 95% respectively at 25 oC. For both solutions, the adsorption of the inhibitor on steel surface corresponds the Langmuir adsorption isotherm, and the nature of adsorption is mainly chemical. All the results show that Salen is a good corrosion inhibitor for protection of steel in both Salty and acidic medium.
