Özet

The corrosion inhibition efficiencies of five different nitrogenous heterocyclic bases 3-amino-1,2,4-triazole (ATA), 2-amino-1,3,4-thiadiazole (ATDA), (p-toly) 1,3,4-triazole (TTA), 3-amino-5-methylmercapto-1,2,4-triazole (AMTA) and 2-aminobenziotriazole (ABA) on carbon steel were investigated in relation to their molecular structure. Corrosion current densities, in the absence and presence of the compounds, were used to assess inhibition performances. The corrosion efficiencies were considered on the basis of their molecular planarity, aromaticity and pi-electron donation assumption.
