description In the present study, the synergistic effect on the corrosion protection properties of Mg alloys subjected to plasma electrolytic oxidation and chemically treated with thiourea as an inhibitor is investigated by surface microstructure analysis, evaluation of the electrochemical performance, and chemical quantum calculations. Physical adsorption of thiourea on the inorganic material surface might be due to physical interaction between thiourea with a low ionization potential serving as an electron donor and the inorganic components with high electron affinities acting as acceptors. The results from potentiodynamic polarization and electrochemical impedance spectroscopy for organic-inorganic coating reveal a clear decrease in the corrosion rate owing to the introduced thiourea.
