| Outline of Final Research Achievements |
In order to develop a high efficient surface finishing method of metal mold made of sintered hard materials including cemented carbide and ceramics by large-area electron beam (EB) irradiation, the effects of EB irradiating conditions on the surface smoothing characteristics, the surface structure, and the surface modification effects were discussed. Experimental and analytical results show that the metal mold surface can be finished to about 1 micron Rz in surface roughness in a few minutes by the large-area EB irradiation. Also, water repellency and releasability molded resin can be improved, since extremely thin resolidified layer with different micro structure from the matrix is formed on the large-area EB irradiated surface.
