摘要：Corrosion can be defined as a phenomenon of physicochemical interaction of a metal and its environment, inducing degradation of the metal itself. Corrosion can be controlled or minimized by the use of inhibitors. To remedy this problem, laboratory research has shown the great interest in using essential oils and extracts of aromatic and medicinal plants, which are natural, non-toxic and renewable products, as corrosion inhibitors. In this review paper, corrosion inhibition of zinc by green inhibitors in various media have been reported. The inhibition’s efficiency of inhibitor compounds is strongly dependent on the structure and the chemical properties of the film formed on the metal surface. The protection of zinc metal from corrosion is analyzed by many technologies such as weight loss (Gravimetric), temperature effect, Gasometric, Potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS). The protective films formed on metal surface have been analyzed by various techniques such as Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), FT-IR (Fourier Transform-Infrared Spectroscopy),UltraViolet(UV)Visible Spectra, X-ray Diffraction Spectroscopy (XRD), Energy Dispersive X-ray Spectroscopy (EDX), Infra-red (IR), Electrochemical Frequency Modulation (EFM), Cyclic Voltametry and adsorption study.
