摘要

The stem extract of Bacopa monnieri (BMSE) was examined as potential corrosion inhibitor of mildsteel in 1 M hydrochloric acid (HCl) media using weight loss, electrochemical and surface studies. Theweight loss results discovered that samples covered with BMSE showed less weight loss compared tothe samples without BMSE. The electrochemical tests including electrochemical impedancespectroscopy (EIS), and potentiodynamic polarization (PDP) showed good mitigation efficiency ofBMSE in 1 M HCl solution. The mixed shift of the anodic and cathodic slopes advised that the inhibitorrepresented as mixed category. The surface studies were completed using scanning electron microscopy-energy dispersive spectra (SEM-EDS) and atomic force microscopy (AFM). Both the studies displayedeven surface in existence of BMSE and rough surface in its absence. All the experimental results are indecent pact respectively.
