Abstract
Weight loss measurements and potentiostatic polarization studies show that 2-hydrazino-6-methyl-benzothiazole (HMBT) acts as an effective in hibitor for the corrosion of mild steel in 1 N HCl and 1 N H2SO4. It b ehaved predominantly as cathodic inhibitor in HCI and mixed inhibitor in H2SO4. Hydrogen permeation studies also show that HMBT acts as an e ffective cathodic inhibitor by decreasing hydrogen permeation current through mild steel surface. The adsorption of HMBT on mild steel from 1 N HCl and 1 N H2SO4 is found to obey Langmuir's adsorption isotherm.
