The influence of azole derivatives on the corrosion of copper in 3% NaCl has been examined through steady-state and weight- loss measurements. Also the impact of the temperature on the efficiency of their action has been determined between 20 and 60 °C. The compounds acted as mixed inhibitors. In the anodic range they acted by building on the copper surface a passive film, more evident with a patented inhibitor (BITA) and diaminotriazole. In the presence of the latter compound, impedance measurements showed a thick film formation, confirmed by EDAX analysis.

Abstract
The influence of azole derivatives on the corrosion of copper in 3% NaCl has been examined through steady-state and weight- loss measurements. Also the impact of the temperature on the efficiency of their action has been determined between 20 and 60 °C. The compounds acted as mixed inhibitors. In the anodic range they acted by building on the copper surface a passive film, more evident with a patented inhibitor (BITA) and diaminotriazole. In the presence of the latter compound, impedance measurements showed a thick film formation, confirmed by EDAX analysis.File in questo prodotto:
