Resumo: | Abstract A new corrosion inhibitor, namely, 1H-1,2,4-triazol-4-amine, 3, 5-diphenyl-N-(phenyl methylene) (HTADP), has been synthesised, and its inhibiting action on ordinary steel corrosion in an acidic media has been investigated by weight loss and various electrochemical techniques. The obtained results revealed that this organic compound is a very good inhibitor. Its inhibition efficiency (IE) exceeded 90%, even at very low concentrations. HTADP was able to reduce steel corrosion more effectively in 1 M HCl. Potentiodynamic polarization studies showed that HTADP is a mixed type inhibitor, predominantly influenced by the cathodic process. The adsorption of this inhibitor onto the ordinary steel surface in 1 M HCl was found to follow the Langmuir’s adsorption isotherm. The adsorption and activation thermodynamic data were determined and discussed. A protective film was formed on the steel surface, which changed the processes at the metal-solution interface. |
