Abstract :ABSTRACT Corrosion inhibition of benzotriazole insert ignore into journalissuearticles values(BTA); for 70/30 brass in 0.1 M NaCl has been evaluated by means of electrochemical polarization and solution analysis.For comparision electrochemical polarization curves were also obtained with zinc and copper electrode. Brass and copper have the same electrochemical properties in BTA containing 0,1M NaCl solution. The anodic responses of the brass in 0.1 M. NaCl containing benzotriazole displays two potential regions. At the first anodic region between -1.0 and 0.0V insert ignore into journalissuearticles values(SCE);, benzotriazole addition Cuinsert ignore into journalissuearticles values(I);BTA film is formed by electron transfer . At the second region between 0.0 V and 0,8 V insert ignore into journalissuearticles values(SCE); copper is oxidized to Cuinsert ignore into journalissuearticles values(I); oxide and Cuinsert ignore into journalissuearticles values(II); hydroxide with the formation of CuCl film. Insoluble Cuinsert ignore into journalissuearticles values(I);BTA film complex is also formed on these oxide/hydroxide films. Key Words: Corrosion, brass,copper, zinc, inhibition, benzotriazole, sodium chloride.
Keywords : Corrosion, brass, copper, zinc, inhibition, benzotriazole, sodium chloride
