Experimental Research on Jet Electroforming

An accurate manufacture technology-electroforming is successfully applied in many high technology fields. But some failings of electroforming, such as low electrodepositing velocity, bad uniformity of depositing lays and so on, badly limit its application and development. This paper designs a experimental equipment for jet electroforming to study the essential technology characteristics on jet electroforming copper. Then the paper analyzes respectively the influence of the technology parameters, such as electroforming voltage, jet flux and nuzzle diameter, on current density and electrodepositing velocity is analyzed the experimental data. The surface quality and texture of the jet electroforming products are studied under different current density situations. Experimental results show that jet electroforming technology can effectively decrease the concentration polarization, increase the current density of cathode, and remarkably improve the quality of deposition layer and obtain more compact crystal structure than traditional electroforming technology under the appropriate conditions.
