The synergistic effect has been studied in the presence of a dicarboxylic acid inhibitor with or without bivalent cation like zinc ions. A protective film has been formed on the carbon steel surface in aqueous solution using a synergistic combination of an environmentally friendly dicarboxylic acid (thiomailc acid) and zinc ions. The corrosion inhibition effect of thiomalic acid with zinc ions on carbon steel has been carried out by gravimetric studies and electrochemical techniques. Potentiodynamic polarization studies reveal that the inhibitor system is of a mixed type. Impedance studies point out that a protective film is formed on the carbon steel surface in the presence of the inhibitor formulation. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to investigate the nature of protective film formed on the carbon steel surface and for explaining the mechanistic aspects of the inhibition process.
