Abstract

The anticorrosive properties of two thiadiazole derivatives, namely 5 amino-1,2,4- thiadiazole (AT) and 2,5 diamino-1,3,4- thiadiazole (DAT) on bronze corrosion in a complex electrolyte at pH=4 has been studied by open-circuit potential,  potentiodynamic polarization, and electrochemical impedance spectroscopy measurements. The results of electrochemical investigations showed that both thiadiazole derivatives protect to some extent the bronze surface from corrosion. In the investigated experimental conditions, the highest inhibition efficiencies values were around 71.3 % and 81.6 % in the presence of 1 mM AT and 10 mM DAT, respectively. The inhibition efficiencies of the organic compounds obtained by electrochemical impedance spectroscopy are in agreement with those obtained from polarization technique.
