Abstract
). The IE% reached 93.4% for compound BTB and 84% for compound DAB at 250 ppm. The equivalent circuit was used to analyze the model of the corrosion inhibition process. The atomic force microscopy image shows the morphology of the adsorbed layer formed on the steel alloy. Finally, a suitable inhibition mechanism was proposed.
