“…Under the investigated conditions, steel acted as an active material with a high corrosion current density, and no protective information formed on the surface, whereas a protective layer was formed in all inhibited surface systems with very low corrosion current densities. 3,11,15 Furthermore, the corrosion potential was strongly shifted to a more negative direction when adding SCLE to the solutions. A significant decrease in i corr (Table 1) was obtained with an increase in the SCLE concentration from 0 to 2500 ppm.…”

“…Natural compounds from plant and vegetable extracts are considered to be green inhibitors of steel corrosion in various aggressive solutions due to their heteroatoms having multiple bonds. These are mostly nitrogen, sulfur, oxygen, and phosphorus atoms with π-electrons, aromatic rings, or long carbon chains in the compound structure. − Interestingly, most of the recent works have focused on compounds extracted from vegetable and plant components for mitigating steel corrosion in different corrosion environments due to the functional groups in the naturally extracted compounds, such as flavonoids, alkaloids, terpenoids, polyphenols, amino acids, and tannins. − These important findings suggest that natural products have promising potential for protecting against steel corrosion and have been vividly characterized and enumerated as green inhibitors from certain leaf extracts, such as Hibiscus sabdariffa, Piper betle, Catharanthus roseus, Luffa cylindrica, Pigeon pea, Ficus racemosa, Ipomea staphylina, Ginkgo, Lannea coromandelica, Olive, Houttuynia cordata, Tinospora cordifolia, Bamboo, and Aganonerion polymorphum . These leaf extracts have demonstrated high protective performance against steel corrosion via organic film formation on the surface.…”

Corrosion Inhibition of Mild Steel in Hydrochloric Acid Environments Containing Sonneratia caseolaris Leaf Extract

et al. 2022

Sonneratia caseolaris leaf extract was characterized for its mitigation of the electrochemical corrosion of steel in naturally aerated hydrochloric acid environments by electrochemical methods and surface analysis. The presence of S. caseolaris leaf extract (SCLE) in the hydrochloric acid medium ameliorated the corrosion resistance of steel via the adsorption of SCLE species to form a barrier layer. The improved inhibition effectiveness was demonstrated to be independent of the SCLE concentration and the corrosive environment. The highest inhibition performance of approximately 98% was reached for steel in a 1 M HCl medium containing 2500 ppm SCLE. The performance significantly decreased with a decrease in the HCl concentration from 1.00 to 0.01 M with the same SCLE concentration. In addition, severe corrosion occurred on the uninhibited steel surface but was significantly reduced on the inhibited steel surface. The analyzed results also indicated the existence of electronegative functional groups in SCLE, which could promote the adsorption process for the self-formation of the barrier layer on the steel surface. The work reported herein suggested a powerful strategy to mitigate electrochemical corrosion by adding an effective new inhibitor to achieve a green inhibitor system.

Anh et al prevented corrosion of steel items by coating a leaf extract of Ficus racemosa with inhibition efficiency of 93% in an acidic medium [ 22 ]. On the other hand, a composite of green plant material with PANI for corrosion protection of metals has arisen as a new interesting topic recently.…”

Potential Impacts of Prunus domestica Based Natural Gum on Physicochemical Properties of Polyaniline for Corrosion Inhibition of Mild and Stainless Steel

et al. 2022

The lack of an eco-friendly approach towards application of polyaniline as a coating material has been one of the most challenging tasks. Herein, the synthesis of green Prunus domestica gum grafted polyaniline (PDG-g-PANI) composite is reported by a cost-effective emulsion polymerization for application as an efficient anti-corrosion material for mild steel (MS) and stainless steel (SS) in a strong corroding environment. The composite formation was confirmed by Ultraviolet Visible (UV-Visible) and Fourier Transformed Infrared (FTIR) spectroscopies. X-ray diffraction data revealed the amorphous nature of the PDG-g-PANI. Scanning Electron Microscopic (SEM) images showed a bi-layered structure having a parent porous layer of PANI coated with afibrous layer of PDG. The solubility test confirmed the dissolution of PDG-g-PANI in common organic solvents such as acetone, ethanol, propanol, butanol, chloroform, N-Methyl-2-pyrrolidone, dimethyl sulfoxide, and the mixture of propanol and chloroform. The polarization curve, open circuit potential, electrochemical impendence spectroscopy (EIS), and gravimetric analysis were applied to investigate the corrosion protection behavior of the composite on MS and SS in 3.5% NaCl and 1 M H2SO4 solution. The PDG-g-PANI-coated MS exhibited 96% corrosion inhibition efficiency as compared to 86% and 43% for pristine PANI and PDG in 3.5% NaCl solution while PDG-g-PANI-coated SS showed 98% corrosion inhibition efficiency. Moreover, 99% and 96.6% corrosion protection was observed for PDG-g-PANI-coated MS and SS in 1 M H2SO4 solution. Gravimetric studies revealed that PDG-g-PANI coating can protect MS up to 93% for 14 days in salt solution while 97% corrosion inhibition efficiency was retained for 2 months in open air.

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.
