“…In contrast, the OCP of the bare Cu foil initially drops off from -130 to -180 mV, probably due to the desolution of copper oxide on its surface, [34] and then gradually stabilizes at about -165 mV (Cu in Figure 6). Tafel analyses have also been carried out to illustrate the corrosion kinetics of the Cu foil with and without the BN nanosheet.…”

Although the high impermeability of graphene makes it an excellent barrier to inhibit metal oxidation and corrosion, graphene can form a galvanic cell with the underlying metal that promotes corrosion of the metal in the long term. Boron nitride (BN) nanosheets which have a similar impermeability could be a better choice as protective barrier, because they are more thermally and chemically stable than graphene and, more importantly, do not cause galvanic corrosion due to their electrical insulation. In this study, the performance of commercially

The inhibiting action of the calyx extract of Hibiscus sabdariffa on mild steel corrosion in 2 M HCl and 1 M H 2 SO 4 solutions was assessed using a gasometric technique. The results demonstrate that Hibiscus sabdariffa extract suppressed the corrosion reaction in both acid media and inhibition efficiency increased with extract concentration with slightly higher values obtained in 1 M H 2 SO 4 . Synergistic effects increased the efficiency of the extract in the presence of halide additives. Adsorption characteristics of the extract were approximated by the Langmuir isotherm. The inhibition mechanisms, estimated from the temperature dependence of inhibition efficiency as well from kinetic and activation parameters show that the extract functioned via mixedinhibition mechanism. It is suggested that molecular as well as protonated organic species in the extract contribute to the observed inhibiting action.

Inhibitive action of Bridelia retusa leaves extract on corrosion of mild steel in acidic media

KEYWORDSExtract of Bridelia retusa leaves was investigated as corrosion inhibitor of mild steel in 1 N H2SO4 using conventional weight loss, electrochemical polarizations, electrochemical impedance spectroscopy and scanning electron microscopic studies. The weight loss results showed that the extract of Bridelia retusa leaves is excellent corrosion inhibitor and electrochemical polarizations data revealed the mixed mode of inhibition. While the results of electrochemical impedance spectroscopy have shown that the change in the impedance parameters, charge transfer resistance and double layer capacitance, with the change in concentration of the extract is due to the adsorption of active molecules leading to the formation of a protective layer on the surface of mild steel. Scanning electron microscopic studies provided the confirmatory evidence of improved surface condition, due to the adsorption, for the corrosion protection.Bridelia retusa Acid corrosion inhibitor Electrochemical polarization Electrochemical impedance spectroscopy Scanning electron microscopy Mild steel
