Abstract: New aspects of molecular interaction in corrosion inhibition are firstly reported in this investigation of 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) on bronze using surface enhanced Raman scattering (SERS). The adsorption on bronze of the corrosion inhibitors 2-amino-5-mercapto-1,3,4-thiadiazole has been characterized in the AMT solution with and without Cl- using electrochemical techniques and surface enhanced Raman spectroscopy. AMT is adsorbed in a perpendicular position at a given concentration. Cl- and AMT are strongly coadsorbed on the surface of bronze in the presence of Cl-.
