提出了一种金属模具大面积电子束光整加工新工艺。在这里使用的大面积电子束辐照设备中，最大直径为60mm的电子束可用于熔化或蒸发金属表面。实验结果表明，随着光束能量密度和辐照次数的增加，辐照表面粗糙度减小，但能量密度过大和辐照次数过多会使表面粗糙度有所恶化。在适当的条件下，表面粗糙度在几分钟内从6 μ m降低到小于1 μ m。表面的光泽度也可以得到很好的改善。通过观察辐照表面的横截面，证实了材料去除仅在
A new finishing process for metal molds by large-area electron beam irradiation is proposed in this study. In the large-area electron beam irradiation equipment used here, the electron beam with a maximum diameter of 60mm can be used for melting or evaporating metal surface. Experimental results show that the roughness of the irradiated surface becomes smaller with increasing the energy density of beam and the number of irradiation, but excessive energy density and too many irradiations make it a little worse. Under a proper condition, the surface roughness decreases from 6 u m to less than 1 ƒÊm in just a few minutes. The glossiness of the surface also can be improved very well. By observing the cross section of irradiated surfaces, it is confirmed that the material removal is performed just on the
