Abstract
Abstract This study investigates the effect of corrosion inhibition of 4-(pyridin-3-yl) thiazol-2-amine (PyTA) on the copper surface. The inhibition efficiencies were evaluated by a series of techniques such as electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, scanning electron microscopy (SEM), and atomic force microscopy (AFM) in various inhibitory concentrations in 1 M HCl solution. The results showed that PyTA can be an effective corrosion inhibitor of copper in an acid solution. According to the EIS approach, the maximum inhibition efficiency (IE%) of 94% is achievable at 1 mM concentration. The adsorption of inhibitor obeyed Langmuir adsorption isotherm. Theoretical studies, namely molecular dynamics (MD) simulation and density functional theory (DFT), were also performed. A comparison of corrosion inhibition of PyTA with our previous work showed that PyTA offers better corrosion protection.
