Mixed-valence compounds are important materials in the field of chemistry and physics due to their excellent physicochemical properties and magnetoelectric effects. Under the protection of nitrogen, the mixed-valence Mn0 x Mn2+ 0.05–x Zn0.95O dilute magnetic solid solutions (5MZO DMSs) are prepared, simultaneously inhibiting both anode and cathode electrochemical corrosion. The penetration and transfer of oxygen are slowed down due to the abundant crystal defects in 5MZO-5 DMS, causing anoxia in the cathode. In addition, plenty of photoelectrons generated by 5MZO-5 DMS inhibit the reaction of iron electron loss, and the path of charge transfer is prolonged due to the excellent magnetic property of 5MZO-5 DMS. Thus, the anticorrosion performance of 5MZO-5 DMS is enhanced to 206.5% compared to that of the ZnO material after 72 h. In particular, the 5MZO-5 DMS is resistant to the rapid corrosion attenuation at high temperatures, meeting the need of anticorrosion under the harsh environment.

“…The fitted model B consists of two circuits connected in series and contains solution resistance (R s ), film resistance (R f ), charge-transfer resistance (R ct ), constant phase element of the film (CPE f ) and of the double layer (CPE dl ). The double layer capacitance (C dl ) can be also calculated from the values of R ct , the impedance of CPE dl (Z CPE ), and the exponents of CPE dl (n) [58]. R f or coating resistance (R c ) is often used for an intact film/coat which act as an isolation layer and provide a good protective performance [59].…”

“…The polarization resistance R p (R p = R ct + R f ) values always keeps higher with increasing concentrations of Harmal extract, which means that it can provide effective corrosion inhibition. It reveals that increasing the concentration results in a more compact passivation film to isolate the iron from dissolution by sulfuric acid ions [58,60].…”

Extract of natural plants is one of the most important metallic corrosion inhibitors. They are readily available, nontoxic, environmentally friendly, biodegradable, highly efficient, and renewable. The present project focuses on the corrosion inhibition effects of Peganum Harmala leaf extract. The equivalent circuit with two time constants with film and charge transfer components gave the best fitting of impedance data. Extraction of active species by sonication proved to be an effective new method to extract the inhibitors. High percent inhibition efficacy IE% of 98% for 283.4 ppm solutions was attained using impedance spectroscopy EIS measurements. The values of charge transfer Rct increases while the double layer capacitance Cdl values decrease with increasing Harmal extract concentration. This indicates the formation of protective film. The polarization curves show that the Harmal extract acts as a cathodic-type inhibitor. It is found that the adsorption of Harmal molecules onto the steel surface followed Langmuir isotherm. Fourier-transform infrared spectroscopy FTIR was used to determine the electron-rich functional groups in Harmal extract, which contribute to corrosion inhibition effect. Scanning electron microscopy SEM measurement of a steel surface clearly proves the anticorrosion effect of Harmal leaves.

“…The compatibility of the anti-corrosive pigment and epoxy resin can be improved by combining HAP and ZnO. In addition, Xue et al [15] proved that the rich hydroxyl in hydroxyapatite could replace free Cl − in the coating to form more stable chlorine apatite and reduce metal damage.…”

With the rapid development of the Chinese marine economy, the anti-corrosion of ships and marine engineering facilities has become urgent to be solved. In this paper, a stable zinc-hydroxyapatite (ZnO-HAP) nanocomposite anti-corrosive pigment was prepared by using the hydrothermal in situ synthesis technique, which supported nano-ZnO onto the hydroxyapatite (HAP) surface. The phase composition, microstructure, and performance of the ZnO-HAP nanocomposite were investigated by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), electron probe microanalysis (EPMA), and electrochemical impedance spectroscopy (EIS), and the anti-corrosion mechanism of the ZnO-HAP nanocomposite was discussed. The results show that the corrosion resistance of the ZnO-HAP/epoxy is better than that of the pure epoxy resin coating. The optimum condition to fabricate ZnO-HAP/epoxy with suitable corrosion resistance was found to be a ZnO/HAP ratio of 0.65/0.35. The synergistic complementation mechanism of ZnO and HAP enriches the metallic anti-corrosion theory and provides a new idea for the synthesis of novel and promising anti-corrosive pigments.
