Copper Casting Layer Prepared by Jet Electroforming

Abstract

Jet electroforming technology was used to make copper casting layer. The effects of current density, electrolyte jet speed and nozzle scanning speed on the surface morphology of copper casting layer have been investigated. Results show that higher current density, scanning speed and lower jet speed produced a compact and smooth copper casting layer with finely deposited particles. However, for opposite electroforming conditions, the copper casting layer was composed of cellular particles growing in dendrite morphology with poor surface smoothness.
