The authors present an overview of the work & results obtained in the framework of a bilateral cooperation program between Belgium and Vietnam to discover new environmentally-friendly corrosion inhibitors or ‘harmless corrosion inhibitors to nature” based on components from naturally-occurring tropical plants. A few hundreds of tests/experiments of a dozen selected tropical plant-extracts as corrosion inhibitors have been performed employing electrochemical impedance spectroscopy (EIS), potentiostatic and potentiodynamic polarization techniques. The efficiency of these extracts, i.e. slow down or reduce corrosion of a metal/alloy when added to a given environment with different concentrations is illustrated.
