Abstract :The electrochemical behavior of the brass electrode insert ignore into journalissuearticles values(Cu-Zn alloy); in a phosphoric aqueous acid solution was investigated. The effect of alternating current density of brass insert ignore into journalissuearticles values(200-1200 A/m2); and titanium insert ignore into journalissuearticles values(20-120 kA/m2); electrodes, phosphoric acid concentration insert ignore into journalissuearticles values(0,5-2,0 M);, electrolyte temperature in insert ignore into journalissuearticles values(20-80 ℃);, AC frequency insert ignore into journalissuearticles values(30-130 Hz);, and for comparition the current density insert ignore into journalissuearticles values(20-120 kA/m2); on pure copper and zinc electrodes are considered. It has been established that by polarization of brass with alternating current with the titanium electrode in an acidic aqueous medium, its dissolve intensively with formation Cu insert ignore into journalissuearticles values(ІІ); and Zn insert ignore into journalissuearticles values(ІІ); ions.
