The use of pulse electrolysis for copper plating on steel and cast iron bases from citrate electrolyte

Process of electrochemical deposition of copper on a steel and iron substrate from citrate electrolytes was investigated. It is determined that the material of cathode greatly influences the kinetics of copper plating process. Influence of pulse electrolysis on a range of working density of current, a current efficiency of copper and porosity of coatings were investigated. It is determined that application of a pulse mode increases a range of working density of current and improves quality of the received coatings
