Abstract

Abstract: For carbon steel (CS) in a corrosive hydraulic acid solution, various quantities of the molecule 3-phenyl-isoxazoline-carvone (PIC) were employed (1M; HCL). The inhibitory effects of the 3-phenyl-isoxazoline-carvone (PIC) were evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), weight loss, surface morphology analysis (SEM), quantum chemical calculations (DFT), and Monte Carlo simulations (MC). According to the findings, the compound, 3-phenyl-isoxazoline-carvone (PIC) is a mixed-type inhibitor that significantly decreased the rate of carbon steel (CS) corrosion by creating a protective coating on the carbon steel surface (CS). According to EIS, PDP, and mass loss studies, the molecule 3-phenyl-isoxazoline-carvone (PIC) is a stronger corrosion inhibitor, with corrosion effectiveness of about 95% at 298 K temperature. Adsorption of the 3-phenyl-isoxazoline-carvone (PIC) molecule on the surface of carbon steel includes both physisorption and chemisorption, according to the Langmuir isotherm model. Aside from experimental methods, theoretical methods such as DFT simulations, molecular dynamics simulations, and the radial distribution method were used to provide detailed knowledge about the mechanism of corrosion inhibition and to reveal factors controlling the efficiency of the investigated inhibitor.
