摘要：

Weight loss measurements and potentiostatic polarization studies show that 2-hydrazino-6-methyl-benzothiazole (HMBT) acts as an effective inhibitor for the corrosion of mild steel in 1 N HCl and 1 N H2SO4. It behaved predominantly as cathodic inhibitor in HCI and mixed inhibitor in H2SO4. Hydrogen permeation studies also show that HMBT acts as an effective 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.
