The hexavalent chromium waste solution after photocatalysis treatment was reused for surface passivation of low carbon steel (sample p-HCC ), to improve its corrosion resistance. The structure and the anticorrosion properties of p-HCC were confirmed by SEM, XPS, electrochemical impedance spectroscopy. Compared with passivation samples treated by pure Cr(III) solution (sample TCC ), the polarization resistance of p-HCC film (2994 Ω cm 2 ) was larger than that of TCC (2043 Ω cm 2 ), which may be due to the higher Cr content in p-HCC film ( p-HCC : 0.71 atom%, TCC : 0.13 atom%), which was caused by a better interaction between Fe ions and Cr-compound due to Cr(VI) residue and photocatalyst in the photocatalysis reduction for hexavalent chromium.

Anticorrosion properties of the wintersweet leaf crude extract (WSLCE) were tested in relationship to the mild steel corrosion in 1 M HCl using gravimetric analysis as well as potentiodynamic polarization and electrochemical impedance tests. The anticorrosive efficiency of WSLCE increased from 76.4% to 91.5% as its content in the solution was increased from 0.1 to 1.0 g/L, respectively. WSLCE behaved as a mixed-type cathodic inhibitor. Extensive characterization of the corrosion products (by SEM, AFM, FTIR, and XPS) showed that WSLCE was adsorbed by the steel surface. Thin WSLCE layer formed on the mild steel surface prevented electron exchange between the steel and HCl, impeding corrosion.

To figure out the behavior of benzotriazole (BTA) loaded in CeO 2 nanocontainers during long term anticorrosion, three kinds of CeO 2 spheres were used: hollow spheres ( HS s), double-shell hollow spheres ( DHS s), and solid-mesoporous spheres ( SS s). The BTA loading and releasing situations were checked, and CeO 2 - HS s exhibited the largest BTA loading amount of 12.5 wt%, forming by both chemical and physical adsorption. The highest BTA loading in CeO 2 - HS s may be attributed to its hollow structure and more Ce 3+ sites (39 %) for BTA anchoring. Thus, CeO 2 - HS s@BTA exhibited an excellent long-term anticorrosion in epoxy coating for low carbon steel protection, showing no rusting after 40 days of salt spray experiment.

The ionic liquids (ILs) are regarded as the ideal candidate for the novel and high-efficiency corrosion inhibitors. While the cost problem caused by relatively large dosage limited the wide employments of conventional ILs. In the current study, we synthesized two novel phosphorus-based ionic liquids (PBILs) with different alkyl chain length (dodecyltriphenylphosphonium bromide (C 12 TPB) and cetyltriphenylphosphonium bromide (C 16 TPB)), and evaluated their anticorrosion efficiencies for mild steel (MS) in 1 M HCl aqueous solution by weight loss measurement, scanning electron microscope, X-ray photoelectron spectroscopy and electrochemical test. The results revealed that PBILs performed excellently (inhibition efficiencies > 93 %) at a very low concentration of 10 μM, which was much greater than those for traditional imidazole and pyridine ionic liquids at 500 μM. It was demonstrated that PBILs could adsorb on the metal surface to form the protective film, which should be mixed corrosion inhibitors with cathodic advantage. Then the adsorption study and molecular dynamics simulation confirmed that their special molecular structure highly promoted the intensity of the adsorption film mainly caused by the chemical adsorption. This study provided a novel approach for the structural design and development of high-performance IL corrosion inhibitors.

h-BN nanoflakes were treated in three plasma gases (Ar、Ar+H 2 (4:1)、Ar + NH 3 (4:1)) for surface modification. The structure characterization (XRD, IR, XPS etc.) of h-BN indicated that the plasma treatment not only enlarged the interlayer distance of h-BN, but also increased the NH/OH surface groups and the ratio of exfoliated h-BN planes. The plasma treated h-BN exhibited better dispersion and stronger Fe 2+ holding ability in acrylic resin than the pristine h-BN, resulting in smaller corrosion current density (i corr ) and larger charge transfer resistance for the acrylic coating on low carbon steel, especially treated in Ar + NH 3 (4:1).

L-Glutathione reduced (GSH) is a small molecule peptide found in large quantities in living organisms, particularly in animal liver cells. Its unique structure gives it great potential to act as an environmentally friendly and efficient corrosion inhibitor. The inhibition properties of GSH for mild steel in simulated concrete pore solutions (SCPS) containing chlorine was investigated by electrochemical tests and SEM-EDS surface analysis. According to the experimental results, GSH mainly blocked the cathodic corrosion reaction and has a corrosion inhibition efficiency of up to 92.3% at room temperature, enhancing the corrosion resistance of mild steel. The isothermal adsorption results indicate that the adsorption behavior of GSH on the surface follows the Langmuir isothermal adsorption model. Both quantum chemical calculations (QC) and molecular dynamics simulations (MD) show that GSH can be effectively adsorbed onto mild steel substrates, thus protecting the surface from erosion. Finally, the results of the above experiments and theoretical calculations are combined to elucidate the inhibitive mechanism: GSH molecules binds to the iron surface via the sulfur, nitrogen and oxygen atoms in the molecule, thus adsorbing to the iron surface in a tiled manner and forming a protective film to prevent the corrosive material from contacting the iron surface.

Corrosion resistance of metals and alloys toward liquid metals determines the service performances and lifetime of the devices using liquid metals. This paper studies the static corrosion behaviors of iron, chromium, nickel, low carbon steel, and four types of stainless steels (SS410, SS430, SS304, and SS316L) in liquid Sb-Sn at 500°C, aiming to screen corrosion-resistant stainless steel for Li||Sb-Sn liquid metal batteries (LMBs). The corrosion rates of Fe and Ni are 0.94 μm/h and 6.03 μm/h after 160 h measurement, respectively. Cr shows a low corrosion rate of < 0.05 μm/h, which is due to the formation of a relatively stable Cr-Sb layer that may be able to prevent the interdiffusion between the solid substrate and liquid Sb-Sn. Ni has a high corrosion rate because the formed Ni-Sb and Ni-Sn compounds are soluble in the liquid Sb-Sn. The corrosion products of both pure metals and SS can be predicted by thermodynamic and phase diagram analysis. Among the four types of stainless steel, SS430 shows the best corrosion resistance toward liquid Sb-Sn with a corrosion rate of 0.19 μm/h. Therefore, a liquid Sb-Sn resistant material should have a high Cr content and a low Ni content, and this principle is applicable to design metallic materials not only for LMBs but also for other devices using liquid Sb- and Sn-containing liquid metals.

Small-molecule organic corrosion inhibitors have attracted extensive attentions, but there are relatively few studies on corrosion inhibitors based on eco-friendly polymer materials. In the present work, dopamine modified polyaspartic acid (PASP-Dop) was well-designed and prepared. The inhibition ability of PASP-Dop towards mild steel was studied at various concentrations and temperatures using electrochemical measurement and weight-loss method. Investigations indicate that PASP-Dop has high corrosion inhibition performance for mild steel in acid solution due to the effective adsorption of PASP-Dop molecules at the metal/solution interface which is found to obey the Langmuir adsorption isotherm. From the potentiodynamic polarization measurements, the inhibition efficiency of PASP-Dop for mild steel in 0.5 M H 2 SO 4 solution at a concentration of 100 ppm is up to 90.9% at 298 K. In addition, effect of temperature performed by weight-loss measurement reveals that PASP-Dop has good temperature adaptability. These results clearly demonstrate that as-synthesized eco-friendly polymer (PASP-Dop) is a high efficiency corrosion inhibitor with good application prospect.

The inhibitive effect of N-lauroyl L-lysine on the corrosion of mild steel in 0.5 M H 2 SO 4 solution was investigated by electrochemical technique, weight loss measurement, scanning electron microscope (SEM) and quantum chemical calculation. The results showed that N-lauroyl L-lysine was a moderate cathodic inhibitor for mild steel in 0.5 M H 2 SO 4 solution with its inhibition efficiency increasing with concentration, and decreasing with temperature. The adsorption of N-lauroyl L-lysine on the surface of mild steel obeyed El-Awady thermodynamic-kinetic model, and the thermodynamic and kinetic parameters, as well as quantum chemical parameters, were determined to discuss the mechanism of inhibition of N-lauroyl L-lysine on mild steel surface.

Background Schiff bases are attractive as eco-friendly corrosion inhibitors for the protection of metals. In this study, a novel volatile corrosion inhibitor (VCI) based on Schiff base (LEU-T) is synthesized from leucine and salicylaldehyde. This study evaluates the volatile corrosion inhibition performance of LEU-T on mild steel and examines its anti-corrosion effect in a simulated atmospheric corrosion solution. Methods The corrosion inhibitor is characterized by Fourier transform infrared (FT-IR) absorption spectra. The corrosion behavior, inhibition efficiency, and anti-corrosion mechanism of the inhibitor on mild steel are evaluated using volatile inhibition ability (VIA) tests, electrochemical measurements (including potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)), and theoretical calculations. Scanning electron microscopy (SEM) and atomic force microscope (AFM) confirm the formation of the inhibitive films on mild steel. Significant Findings The results demonstrate that LEU-T exhibits outstanding inhibition efficiency of 82.18 % in VIA tests. Electrochemical measurements indicate that the formed inhibitive films on the steel substrate lead to an increase in the charge transfer resistance. The corrosion inhibition efficiencies of leucine and LEU-T, as determined by electrochemical impedance spectroscopy, are 67.84 % and 83.90 %, respectively. SEM and AFM observations indicate that the inhibitor forms a protective VCI coating, effectively retarding the steel corrosion. The LEU-T has larger adsorption energy (-136.13 kJ/mol) compared to leucine (-88.48 kJ/mol) on mild steel.

The inhibitive ability of 2,6-diaminopyridine, tartaric acid and their synergistic effect towards mild steel corrosion in 0.5 M HCl solution was evaluated at various concentrations using potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and weight loss experiments. Corresponding surfaces of mild steel were examined by atomic force microscope (AFM), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) analysis. The experimental results are in good agreement and reveal a favorable synergistic effect of 2,6-diaminopyridine with tartaric acid, which could protect mild steel from corrosion effectively. Besides, quantum chemical calculations and Monte Carlo simulation were used to clarify the inhibition mechanism of the synergistic effect.

Inhibition performance of omeprazole for mild steel in 0.1M H2SO4 solution has been investigated through different approaches including potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), weight loss, scanning electron microscope (SEM) experiments and theoretical calculations. The experimental results reveal that omeprazole is an effective inhibitor with a maximum achievable inhibition efficiency of 98.5%, and the adsorption of omeprazole on the mild steel surface is found to obey the Langmuir adsorption isotherm. Polarization curves illustrate that omeprazole acts as a mixed-type inhibitor, and EIS demonstrates that an adsorption film of the inhibitor is formed on mild steel surface. Moreover, quantum chemical calculations and the molecular dynamics (MD) simulation are also performed to gain the further insight of the inhibition mechanism of omeprazole on steel corrosion, which show that the possible adsorption centers of the omeprazole molecule are benzene ring, benzimidazole ring, sulphinyl and the nitrogen atom of the hexaheterocyclic.
