Assessing the corrosion protection of 8-hydroxyquinoline-cerium (III) complex for carbon steel in a NaCl solution

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.

Quantum mechanical and electrochemical investigations on corrosion inhibition properties of novel heterocyclic Schiff bases

The corrosion inhibition efficiencies of two novel Schiff bases, namely (E)-3-[thiophen-2-lmethyleneamino]benzoic acid (T2YMABA) and (E)-4-(5-[(2-phenylhydrazono) methyl]thiophen-2-yl)benzoic acid (PHMT2YBA) on mild steel (MS) in 1.0M HCl solution has been investigated and compared using electrochemical impedance spectroscopy and potentiodynamic polarization analysis.
