“…These results reveal that the addition of the P. terminalis extract reduces anodic metal dissolution and it also retards cathodic hydrogen evolution to a greater extent. The corrosion kinetic parameters depicted in Table I show that the cathodic Tafel slope ( b c ) values and anodic Tafel slope ( b a ) values vary slightly, specifying the tendency of an inhibitor to impede corrosion on metal on both anodic and cathodic sites representing the mixed mode of inhibition (Aejitha et al , 2016). These results reveal that the P. terminalis extract prevents corrosion by impeding the cathodic and anodic reactions because of the formation of a barrier film which reduces the effective area available for the corrosion process.…”

Purpose The study aims to find new anticorrosive components from a plant source, namely, Pachysandra terminalis Sieb. et Zucc. (P. terminalis), a traditional medicinal shrub predominantly used by Tujia people. Design/methodology/approach Because phenolic components from plants are known for its numerous values in several fields, the corrosion inhibitive ability of P. terminalis extract was analyzed by electrochemical studies (polarization, electrochemical impedance spectroscopy) and surface examination (by scanning electron microscopy [SEM], energy-dispersive X-ray spectroscopy [EDX] and atomic force microscopy [AFM]). Findings The examination of total phenolic content (TPC), total flavonoids content (TFC) and individual phenols (UHPLC) showed the presence of 85.21 mg/g (TPC), 25.38 mg/g (TFC), protocatechuic acid (62.10 µg/g), gentisic acid (60.21µg/g), rutin (50.12 µg/g), kaempferol (46.58 µg/g) and p-Coumaric acid (42.35µg/g) . The polarization study shows that the maximum shift is (16 mV), imposing a mixed mode of inhibition, dominantly anodic. The surface morphology studies by SEM, EDX and AFM confirmed the adsorption of phytochemical components on the low carbon steel surface blocking the active sites. Originality/value The study unveils the inhibitive nature of P. terminalis, preventing aggressive attack by 0.5 M HCl on low carbon steel. This also exhibits few phenols present in methanolic leaf extract which may be the role player of corrosion inhibition.

“…due to inexpensive productivity and exhibition of some unique physical properties. 1,15 Despite the utility of these metals, their exposure to the environment brings about adversities such as chemical reactions from compounds of different sources lead to the deterioration or degradation of their components. One of the processes is corrosion which causes several economic-related consequences and environmental pollution.…”

Mild steel has excellent applicability to structures that provide many benefits to man. On the other hand, exposure to chemical reactions including corrosion leads to their degradation. Thus, minimizing the effect of such phenomenon (corrosion) is needed (since it is a natural process). This study aimed to determine the corrosion inhibition of Diospyros blancoi (velvet apple) acid leaf extract on mild steel in an acidic medium. Further, it determines the concentration at which D. blancoi acid leaf extract (DbAE) performs best in corrosion inhibition parameters. Acidic environment immersion was done on mild steel sheets on treatments with different DbAE concentrations (5%, 10% and 15%). Weight loss was the factor determined to determine the inhibition efficiency of the DbAE concentrations and the corrosion rate of the mild steels. Results showed that the inhibition efficiency is highest and the corrosion rate of mild steel is lowest at 15% DbAE concentration. It is recommended that sophisticated facility/ equipment be used to determine the effect of DbAE on the physical and chemical components of mild steel. Also, the production of D. blancoi must be done since the potential anticorrosion impact of this plant species has been determined.
