Porous Metal and Method for Preparation by the Scanning and Swinging Jet Electrodeposition

The preparation of porous metals by a novel scanning and swinging jet electrodeposition (SSJED) technology with computer numerical control of the 3D motion trail of the jet nozzle was studied. The morphology and mechanical property of deposits prepared by SSJED under different scanning parameters were examined. The results indicated that porous metals could be produced by SSJED with excellent control of the structure by guiding the dendrites growth in desired directions. The dendrites in deposits failed to be connected and interweaved with each other completely with low swinging times of the nozzle. As swinging times increased, the connection and interweaving of dendrites were effectively achieved, following with the gradually coarse branches on the horizontal interweaving point.
