Triazepines Compounds as Novel Synthesized Corrosion Inhibitors: State of Play and Perspectives

Abstract

This chapter describes some recent good works in the field of metallic corrosion monitoring using Triazepine carboxylate inhibitors in hydrochloric acidic media. The different sections of this chapter cover electrochemical measurements and theoretical investigations. This review reveals Triazepine carboxylate compounds as very good inhibitors for mild steel in hydrochloric medium. The inhibition action of all Triazepine carboxylates compound studied was performed via adsorption on mild steel surface. Comparison between several adsorption isotherms reveal that the adsorption was spontaneous and followed Langmuir isotherm in HCl for all inhibitors and all studied temperatures. Kinetic and thermodynamic parameters for all inhibitors led to suggest the occurrence of chemical mechanism and also the spontaneity of the adsorption process on mild steel surface. The corrosion inhibition mechanism was also compared and discussed with the light of some Triazepine carboxyale compounds constituents.
