Research Abstract |
This study aims to develop a new process for surface finishing and surface modification of metal mold by large-area short-pulse EB irradiation. Effects of EB conditions on the surface structure and the surface characteristics were experimentally discussed. TEM observation and EDX analysis clarified that a thin resolidified layer with the different micro structure from the matrix was formed on the surface. The water repellency and the resistance to corrosion could be improved by large-area short-pulse EB irradiation and also they could be controlled by the EB conditions.
