Abstract
2-amino-5-mercapto-1, 3, 4-thiadiazole is a new inhibitor to resist the corrosion of copper and its alloys. The corrosion behavior of bronze in the presence of AMT has been investigated in 5% citric acid. Electrochemical potentiostatic polarization method and electrochemical impedance spectroscopy (EIS) were applied to analysis the effect of the organic compound on the corrosion inhibition of bronze. The results showed that AMT could greatly retard the corrosion of bronze in citric acid, which was attributed mainly to the protective film formed by AMT. Fourier transform infrared (FTIR) was used to characterize the surface film. A polymeric Cu (I) -inhibitor complex exhibiting strong corrosion inhibition that totally covered the bronze surface was identified. AMT behaves as bidentate ligand through the aminic nitrogen atom and the closed ring nitrogen in these complexes.
