摘要：
The inhibition ability of an imine compound (PTM) and its cobalt complex (CoPTM) towards low carbon steel (LCS) corrosion in HCl solution was studied at various concentrations and temperatures using potentiodynamic polarization curves (Tafel), electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM), and energy-dispersive X-ray spectroscopy (EDS) methods. Electrochemical measurements showed that the inhibition efficiencies of both PTM and CoPTM depend on concentration, temperature, and immersion time. An adsorption mechanism for PTM and CoPTM on the LCS in 1 M HCl solution was proposed and discussed. Electrochemical results confirmed that the adsorption of CoPTM was stronger than PTM.
