“…Various studies has been reported recently regarding the inhibition efficiency of different plants extract against steel corrosion: Holoptelea integrifolia leaves [9], lychee fruit [17], Curcuma longa extract [18], Aloe Vera leaf [19], Thymus Vulgaris [20], Egyptian licorice [21], Coreopsis tinctoria [22]. Among plant materials tested in our laboratory are: Bupleurum lancifolium (Apiaceae) [23], Saccocalyx satureioides [24], Thapsia villosa [25], Echium italicum L [8], Reutera lutea (Desf.) Maire (Apiaceae) [26].…”

The current investigation presents the corrosion activity of Elaeoselinum thapsioides (BEET) butanolic extract in 1 M HCl as a novel green source of corrosion inhibitor, and it's synergetic effect with another butanolic extract of Reutera lutea (BERL), whose belongs to the Apiaceae family. Weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements have been done to study the inhibition efficiency. The obtained results showed that the inhibition efficiency of BEET alone increase with concentration and reached a value of 82% at 900 ppm. However, the maximum protection efficiency was more than 92% with the combination of BEET and BERL inhibitors. The rise of temperature caused a significantly decreased of inhibition efficiency. The potentiodynamic polarization results revealed that the extract functions as mixed-type inhibitor with predominance at anodic domain, and the adsorption process of the extract follows Langmuir isotherm. In addition, EIS shows that increasing the concentration of the inhibitor leads to an increase of the charge transfer resistance and reducing the double layer capacitance. The synergistic factor (S) was used to investigate the synergistic behavior of the selected inhibitors.

We highlight in this chapter the corrosion protection using phenolic extract. The building of mathematical models using experimental results obtained from the investigation of phenolic molecules or fractions extracted from Echium italicum L., used as corrosion inhibitors is one of the new trends in the study of steel protection. The evaluation of the corrosion inhibition of carbon steel (API 5 L-X60) in a solution 1 M of hydrochloric acid was performed using gravimetric method, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The predicted mathematical relationships between the corrosion rate and the inhibitory efficiency in the presence of the butanolic extract of Echium italicum L. (BEEI), when increasing temperature proved a good agreement between experimental and mathematical studies.

In 1 M HCl pickling media, the paprika extract was used as an ecofriendly anti-corrosive material for carbon steel. Many strategies were utilized to estimate the mitigation efficacy such as potentiodynamic polarization (PP), frequency modulation (EFM), electrochemical impedance spectroscopy (EIS), and mass loss. Surface analyses were accomplished by scanning microscopy (SEM) and dispersion X-ray (EDX) techniques. The mitigation efficacy ameliorates with the concentration of extract and temperature. The inhibition is ascribed to the building of a protective coating at the surface of carbon steel that reduces its dissolution. The adsorption of Paprika extract on steel metal satisfied Langmuir , s model. The adsorption belongs to the physical and chemical types. The adsorption of the extract affected both anodic and cathodic reactions. Tafel curves demonstrated that the Paprika is a mixed inhibitor. The Nyquist curves confirmed that Paprika extract prohibits the disintegration of steel in acid media without changing the dissolution reaction mechanism. The adsorption of the Paprika extract on the carbon steel metal was confirmed by ATR -FTIR analysis and SEM examination. Using 300 ppm of Paprika extract, a maximum inhibitory efficacy of 95% was observed at 313 K.
