摘要：The influence of Salix babylonica extract (SBE) on carbon steel (CS) corrosion in 1molar HCl at 25°C has been investigated. Mass loss (ML) method, Tafel polarization(TP), AC impedance (EIS) and electrochemical frequency modulation (EFM) tests havebeen used to derive the corrosion parameters. The data obtained from both tests (EISand EFM) are comparable with those obtained from Tafel extrapolation tests, approvingconfirmation calculation of corrosion rates of the final. The inhibiting action of SBEwas discussed in terms of blocking the CS surface by molecules adsorbed on the activesites. The adsorption was found to obey Temkin isotherm. The morphology of protectedand unprotected CS has been examined by different techniques like: Fourier transforminfrared spectroscopy (FTIR), scanning electron microscope (SEM), energydispersive X-ray (EDX) and atomic force microscope (AFM).
