A study of supersonic-aided electrolysis

In this study, a composite processing technology combined with supersonic and electrochemical machining is adapted to etch copper. Rod copper of diameter 3.0 mm is selected as a sample material. A series of experiments of supersonic-aided electrolysis by agitating anode, and electrolyte were carried out to investigate performance for copper etching. Faster metal removal rate can be achieved in supersonic-aided electrolysis machining by agitating either the anode or electrolyte. Removal rate can be raised up to 65% by supersonic-aided electrolysis by agitation both of anode and electrolyte. Deposition speed of cathode is lower in supersonic-aided electrolysis. Machined surface roughness of workpiece by supersonic-aided electrolysis is much better than no agitation.
