| 研究開始時の研究の概要 |
The EP process is carried out in a eutectic mixture consisting of choline chloride and propylene glycol and, alternatively, ethylene, and the workpiece is 316L SS parts fabricated by SLM with designed micro-texture on surface. Five stages constitute the research plan, including development of experimental setup, fabrication of micro-textured surface by SLM and EP the fabricated parts, fundamental study of EP with DESs and pulse voltage, and EP micro-textured surface.

| 研究実績の概要 |
Aluminum samples were additive manufactured with different laser conditions, such as the scan speed, hatch distance, scan interval, and laser power. The effects of various laser conditions on the electropolished surface were studied. It was found that the laser power was of critical importance for the electropolished surface quality. This is because the final polished surface is closely related to the initial surface quality which was mainly determined by the applied laser power.
