摘要：

In this study,, the employment of Ashwagandha extract (AE) as a green sustainable corrosion inhibitor for aluminum in one molar hydrochloric acid solutions was examined utilizing "mass loss (ML), electrochemical frequency modulation (EFM), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) measurements", The surface examination was analyzed utilizing atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) analysis, The effect of temperature on corrosion demeanor with adding a different dose of AE was insvestigated within the temperature varieties of 25-45 degrees C by ML strategy, The curves of polarization reveal that AE is considered as a mixed sort inhibitor. The performance of inhibition rises kith raising the AE concentration and diminished with the temperature ascending. The adsorption of the inhibitor on aluminum surface complies with the Langmuir's adsorption isotherm and is considered as physisorption, The outcomes attained from chemical and electrochemical methods are in good accord,
