Abstract :
The effect of new corrosion inhibitors namely N-[1-(benzotriazol-1-yl)ethyl]aniline (BTEA), and N,N-dibenzotriazol-1-
ylmethylaminoethane (DBME) on the dezincification of 65–35 brass in sodium chloride solution was investigated using weightloss
measurements and electrochemical techniques such as potentiodynamic polarization and electrochemical impedance
spectroscopy. Results obtained revealed that these compounds were very good inhibitors and behaved better in NaCl solution.
Polarization studies showed that the BTEA and DBME behave as a mixed-type of inhibitors for 65–35 brass in sodium chloride
solution. They decrease the anodic reaction rate more strongly than the cathodic reaction rate and renders the open circuit
potential of brass more positive in NaCl solutions. Solution analysis revealed the decrease in dissolution of both copper and zinc
in the presence of these inhibitors
