2-Aminobenzothiazole as an efficient corrosion inhibitor of AA6061-T6 in 0.5 M HCl medium: electrochemical, surface morphological, and theoretical study

Abstract The inhibitive action of 2-aminobenzothiazole (ABT) on the corrosion AA6061-T6 was evaluated in 0.5 M HCl by electrochemical techniques. results were validated theoretical calculations using density functional theory (DFT). ABT showed a mixed inhibitor behaviour with 71–90% inhibition efficiency 1 × 10 ?4 to ?3 concentration range and at 303 323 K temperature. power increases its rise temperature medium. polarization reduction rate improvement performance increasing concentrations, which reveal ABT's adsorption alloy. evaluation kinetic thermodynamic revealed that inhibits adsorption, following Langmuir isotherm model. observed increase resistance increased concentrations indicates attenuation deterioration. Furthermore, corroded inhibited specimen's surface scanning is performed confirm alloy sample electron microscopy (SEM) atomic force (AFM) Graphical abstract
