Abstract: The corrosion-inhibiting behavior and adsorption of Venlafaxine on mild steel has been examined using 1 M HCl at 298 K. Techniques used include weight loss studies, potentiodynamic polarization studies, electron impedance spectroscopy, computational studies (Monte Carlo simulation studies) and AFM studies. The polarization data revealed that Venlafaxine mostly behaves as mixed type of inhibitor. The data from weight loss results suggested that inhibition efficiency varied directly with concentration and inversely with temperature. A quantum chemical calculation and molecular dynamic (MD) simulation studies were used to further validate inhibition mechanism.
