The pattern of the electrochemical ionization and passivation of Cu 62 Zn brass in chloride solutions with different compositions is studied. It is shown that the electrochemical dissolution of Cu 62 alloy in concentrated chloride solutions is controlled by ionization of the copper component in the alloy. There was studied the selectiveness of Cu 62 Zn brass component dissolution and modification of the alloy surface at electrochemical dissolution in chloride solutions.
