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

摘要

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. Themorphology and mechanical property of deposits prepared by SSJED under different scanningparameters were examined. The results indicated that porous metals could be produced by SSJED withexcellent control of the structure by guiding the dendrites growth in desired directions. The dendritesin deposits failed to be connected and interweaved with each other completely with low swingingtimes of the nozzle. As swinging times increased, the connection and interweaving of dendrites wereeffectively achieved, following with the gradually coarse branches on the horizontal interweavingpoint.
