In this study, the TiO2 passive layer was formed on a pure titanium substrate by simple oxidation in an aqueous solution of H2O2 35 wt.%. In order to determine the appropriate time for the oxidation of the pure titanium substrate, the corrosion rate of the metal in the solution of H2O2 was investigated. The electrochemical behaviour of the TiO2 passive layer on the Ti substrate was investigated in Hank’s solution at 37.5°C.

In the present study, a complex between 8-hydroxyquinoline and cerium (III) (CeHQ) was synthesized in the presence of triethylamine. Afterwards, the complex was characterized by Field Emission Scanning Electron Microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR) and Thermo-Gravimetric Analysis (TGA). The inhibition efficiency of the Ce-HQ complex for the corrosion of carbon steel, evaluated by both Electrochemical Impedance Spectroscopy (EIS) and Potentiodynamic Polarization (PP) plots, reached 90 % after 2 h of immersion in a 0.01 M NaCl solution.

This work presented the corrosion protection performance of anticorrosion multi-metal hybrid (AC-2MH) complex additive for solder materials in corrosive media. The AC-2MH complex contained traditional additives and organic acids. The Electrochemical impedance spectroscopy results demonstrated the formation of active and passive protective layers on the surface of the alloys, which prevented the solder materials from corrosion.

Impedance measurement was used to quantify the amounts of PbSO4 and PbO in the initial stage of the oxidation. H3BO3 decreased the positive grid corrosion of all alloys, while impurities increased it. Although impurities increased the self-discharge during constant current discharge, H3BO3 was found to decrease it, except for the alloy containing the 3 impurities and the Cu-containing alloy. Under open-circuit conditions, H3 BO3 increased significantly the self-discharge rate, but impurities were found to suppress it.

The corrosion inhibition of mild steel alloys is of tremendous technological importance due to their increased industrial applications. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques were used to establish the effect of different concentrations of HCl on the corrosion behavior of mild steel. A study was conducted on the inhibition of dissolution for a mild steel alloy in the most corrosive concentration of HCl (5 M) by adding different concentrations of aqueous extract of Hibiscus sabdariffa plant (named karkade or rosselle) as an ecofriendly inhibitor.
