Abstract Some new triazole based corrosion inhibitors namely, 4-henzylideneamino-3-hyrkazinoS-mercapto-l,2,4-triazole, OlAHMT), 4-dimethylaminohellzylident'amino-3-hyrlrazino-5-mercapto-l,2,4triazole (DAHMT), and 4-vanillideneamino-3-hydrazino-5-mt'rcapto-1,2,4-triazole (VAH MT) have heen synthesi:ud and their innuence on corrosion inhihition of mild steel in 15% hydrochloric acid solution under boiling conditions has heen studied using weight loss method. All the tested inhihitors except DAHMT showed 90% inhibition efficiency. Jlotentiodynamie polarization measurements have Iwen carried out at room temperature, which clearly reveal the fact that all investigated inhihitors are of mixed type and they inhihit corrosion of mild steel hy hlockin~ the active sites of the metal surface. 'nil' adsorption of these inb.ihitors on the mild steel surface from 15% Het has been found to ohey Temkin's adsorption isothenu.
