| Abstract | ||||
| The inhibition impact of freshly created allyl rhodanine azodye derivatives inhibitors (1-3) on C-steel and their adsorption patterns in 2 M HCl were investigated were investigated using weight reduction strategy, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), electrochemical frequency modulation (EFM) techniques, and scanning electron microscopy (SEM). The total resistance of the carbon corrosion process and inhibition efficiency of compounds (1-3) was increased with the increase of the inhibitor concentration. The corrosion rate reduced as the percentage of the compounds in the HCl solution increased, according to Tafel polarisation curves.The inhibition impact of freshly created allyl rhodanine azodye derivatives inhibitors (1-3) on C-steel and their adsorption patterns in 2 M HCl were investigated were investigated using weight reduction strategy, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), electrochemical frequency modulation (EFM) techniques, and scanning electron microscopy (SEM).
