Abstract
:
Abstract. The effect of five S-alkylisothiouroflium iodides on the corrosion of steel in 1.0M HCl was investigated. Gasometry, mass-loss and d.c. polarization techniques were used at 30°C for chemical and electrochemical studies. The chemical study was also used to investigate the effect of temperature in the range (30°C ـــ 70°C). The obtained data showed that the inhibition efficiency of the studied compounds was increased with the increase of chain length of the additive alkyl group. An adsorption mechanism was also suggested for the inhibition process by those compounds. The thermodynamic constants: free energy of adsorption, activation energy, enthalpy and entropy of activation and Tafel constants were also recorded.
