Outline of Final Research Achievements

We developed electrode manufacturing technology to move the insulating material to the workpiece surface by pulsed discharge and carried out the electrode material movement test. Zn (zinc) which is a low boiling point material was used as a binder and carrier medium in order to move the insulating material to the workpiece. Discharge was generated between the electrode and the workpiece, and the insulating material was transported to the workpiece. By miniaturizing Zn, it was possible to melt the electrode material and adhere it to the surface of the workpiece even with a discharge pulse of small energy. The ratio of Zn in the deposit on the workpiece could be reduced to about 1%. As an example of a functional insulating material, a luminescent material was successfully deposited on the workpiece surface, and a luminescence test was also conducted.
