عنوان انگلیسی Omeprazole's Inhibitive Activity on the Corrosion of the Al Alloy in 0.5 M H2SO4 Solution
چکیده انگلیسی مقاله Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques were used to examine the inhibitory effect of omeprazole (OMP) on the corrosive behavior of Al-Mg-Si alloy in 0.5 M H2SO4. SEM/EDS microscopy methods and
X-ray diffraction (XRD) analysis were utilized to examine the surface morphology. According to the findings, OMP acted flawlessly as an inhibitor of corrosion for an Al-Mg-Si alloy in 0.5 M H2SO4 at 298 K. The effect of temperature on inhibition efficiency was also discussed. Moreover, the experimental results suggest that OMP is an effective inhibitor, with a maximum inhibition efficiency of 90.5% at a concentration of 1.5 g/L, and the potentiodynamic polarization curves show that it is a mixed-type inhibitor. Electrochemical impedance spectroscopy discovered that an inhibitory adsorption film was being formed on the surface of the Al-Mg-Si alloy, and that this adsorption isotherm model is being followed. Thermodynamic activation parameters have been identified and discussed.
