The corrosion inhibition of carbon steel in 1.0 M HCl using the Aloes leaves extract has been studied. Three electrochemical different techniques have been utilized for studying the corrosion inhibition efficiency behavior of Aloe vera Gel as green corrosion inhibitor in addition to Scanning electron microscopy-Energy dispersive Xray analysis (SEM-EDX) technique. The four techniques which are potentiodynamic polarization, Electrochemical impedance spectroscopy (EIS), Electrochemical frequency modulation (EFM) and SEM-EDX were used for evaluation at room temperature 25 ᵒ C. The results show a good efficiency with low concentration of inhibitor, where the electrochemical methods show that 52 % efficiency with low concentration 100 ppm, in addition to surface morphology of carbon steel show a protected surface compared with noninhibited specimen due to formation of inhibitor layers on surface. EDX show that more concentration of chemical elements of gel extract chemical components adsorbed on inhibited specimen compared with non-inhibited specimen. The inhibition efficiency increases with the increasing of the aloe vera gel concentration.

“…On the other hand, on addition of TAB, the values of E corr shifted to the positive region similar to OCP values. However, even the highest shift is not up to ± 85 mV which is the benchmark for classification as anodic or cathodic corrosion inhibitor [49]. This implies that TAB acts as mixed type inhibitor and influences both cathodic and anodic half reactions, but exhibits dominant influence on anodic reaction [50].…”

Tabersonine (TAB) is demonstrated as ecofriendly new material that inhibits of pipeline steel corrosion in both acid and microbial (Desulfovibrio sp) environments. At 0.85 mg/mL (2.5 mM) minimum inhibitory concentration (MIC), TAB inhibits bio-corrosion induced by the sulphate-reducing bacteria (SRB) with efficiency of 61.9% and 51.9% at 30 °C and 60 °C, respectively. Also, 10.0 mM TAB is 90.8% and 88.1% efficient in inhibiting corrosion of X80 steel in 1 M HCl at 30 °C and 60 °C, respectively. FTIR, SEM/EDS, local selectivity and adsorption studies at computational level confirm that TAB molecules can provide surface protection by spontaneous physical and chemical adsorption on steel surface via O, N and C=C sites. TAB serves as mixed type inhibitor with dominant influence on anodic reaction; its addition to the acid solution reduces surface roughness by 46.7%. Instead of using different materials for mitigation of microbial and acid induced corrosion, TAB can be a cost effective, efficient alternative.

“…Natural product extracts have been proposed in the last years as an alternative to be used as corrosion inhibitors due to having their chemical compounds such as aromatic rings, OH-groups, and heteroatoms (N, O, S, and P) [1,2] which make them an excellent alternative to replace the synthetic organic and inorganic compounds currently used as corrosion inhibitor since well know that they can reduce the corrosion rate due to in their chemical structure exist the compounds mentioned before [3]. Also, the extraction methods used to obtain the active compounds are cheap and easy to carry out, such as Soxhlet, maceration, hydro distillation, and so on [4][5][6].…”

The hexane extract of Persea Schiedeana Ness (PSN) was analyzed as corrosion inhibitor for the brass surface immersed in 0.5 M HCl. Fourier-transform infrared spectroscopy and a gas chromatographic (GC) and mass spectrometric (MS) were used to identify the PSN extract´s functional groups and compound constituents. The functional groups identified were CH3 and CH2 functional alkyl groups, C = O stretching vibration of aldehydes, ketones, and carbonyl groups found in flavonoids and fatty acids. The GC-MS determined the presence of fatty acids in the PSN extract, where palmitic acid, oleic acid, and ethyl oleate were the major constituents. Electrochemical characterizations were conducted to observe the effect of the hexane extract of PSN as corrosion inhibitor on the brass surface. The Rp and Rn calculated from EIS and ENA give the same behavior with magnitude values near each one. Based on the OCP behavior, it was determined that the PSN works as a mix inhibitor affecting both anodic and cathodic reactions. The corrosion current density (Icorr) determined with the Potentiodynamic test suggests that the extract of PSN reduces the corrosion rate of the brass with efficiencies above 90% for all concentrations. The efficiency obtained for each PSN concentration was attributed to forming a corrosion scale of CuO and Cu2O, which reacted with the carboxyl group to form copper carboxylates on the metal surface.
