The book presents the latest data on the processes of metal deposition by reversed current. The scientific achievements of domestic and foreign researchers are summarized, as well as the experience of the industry in applying the new principle of electrodeposition of metals in order to intensify galvanic processes and improve the protective properties of coatings. A significant place in the book is occupied by the author's research. The following processes of coating with reversed current are considered: copper plating, nickel plating, iron plating (cooling), chrome plating, zinc plating, cadmium plating, tin plating, silver plating, gilding, platinum plating, as well as electrodeposition of alloys. Along with the description of theoretical processes, considerable attention is paid to the description of their practical implementation and familiarization with the latest equipment for current reversal. The book is intended for a wide range of galvanosteg specialists, research engineers to protect metals from corrosion, as well as university students specializing in this field.
