Abstract

Inhibition of Type 304 L SS corrosion in 0.5 M HCl by New Fuchsin is reported using potentiodynamic polarization, electrochemical impedance spectroscopy, scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) techniques. The study was complemented by DFT calculations and Monte Carlo simulation (MCS), and the data were interpreted in terms of the Point Defect Model (PDM) and the Anion-Catalyzed Active Dissolution Model (ACADM). Both account for the experimental data. DFT and MCS simulation show that aromatic rings and -NH₂ groups interact with the Cr₂O₃ surface and the inhibitor adopts a lateral configuration on the surface.
