The effect of 4,6-dimethyl-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid (DODHPCA) as a corrosion inhibitor for C-steel in acetic acid is examined by using hydrogen gas evolution, mass loss and potentiodynamic polarization techniques, as well as SEM investigation. Results showed that, the compound under study exhibits inhibitor properties. The inhibition efficiency was found to depend on the inhibitor concentration. The inhibition effect is based on the adsorption of DODHPCA molecules on the metal surface following Langmuir adsorption model. Tafel polarization curves indicated that this compound was of a mixed-type. The thermodynamic parameters are calculated and discussed.
