Corrosion protection

Reduced graphene oxide (Gr) has been synthesized electrochemically on the surface of copper metal at a fixed potential of 1.5 V versus a standard saturated calomel electrode (SCE). The synthesized Gr was then characterized with X-Ray diffraction, thermogravimetric analysis, raman and Fourier transform infrared (FT-IR) spectroscopies.

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.

Corrosion can be controlled by isolation of the metal from the corrosive environment. Isolation of corrodible metals from corrosive environments is probably the most general method of the corrosion protection afforded by paint films, sealers and lining on base materials. Fluoropolymers provide superior chemical resistance and are used in a variety of markets.
