Effect of 1,2,3- triazole derivative on the dissolution performance of mild steel in 1M HCl medium

Vijayalakshmi, K ; Elangovan, J

Abstract

The corrosion mitigation behaviour of 1-benzyl-4-(naphthalen-2-yl)-1H-1,2,3-triazole (BNT) has been explored on mild steel in 1M HCl medium employing chemical and electrochemical techniques. The observed results illustrate that the hindered efficacy was increased as increasing concentration of BNT and with rising temperatures. The electrochemical studies point out that the inspected BNT is a mixed kind inhibitor and the adsorption isotherm discussions proposed the inhibition mechanism obeyed Langmuir isotherm. The kinetic and thermodynamical parameters exposed that the adsorption process is endothermic, spontaneous and the mechanism is both physical and chemical adsorption. Further, the morphological investigations have been carried out by SEM, EDS and AFM techniques. The highest efficiency perceived for BNT is found to be 91.35% and behaved as a proficient inhibitor against mild steel corrosion in the 1M HCl environment.
