The Effect of Cathode Surface Treatment on the Properties of Electrodeposited Copper Powders

The main attention is paid to the study of processing mechanisms the surface of the electrode affects the kinetics of the electrodeposition of metals from various solutions of their complex salts, as well as improving the technology of obtaining electrolytic powder. Special attention was paid to the detailed study of regularities of the processes occurring during the electrodeposition of copper. Discussed features of the processes of separation of copper powders from solutions of ammonium chloride with addition of complexing polymers of polyacrylamide and polyvinylpyrrolidone's. The basic laws of surface treatment are considered cathode and processes affecting the kinetics of electrodeposition of metals various factors on the particle growth rate and purity of the resulting powders. Researches on improvement of technology of receiving and the intensification of the processes of electrodeposition of copper powders from complex electrolytes'.
