| 摘要: |
| 利用自行研制的混粉电火花镜面加工装置，以淬火状态的8407模具钢为例，对多种添加粉末下的混粉电火花镜面加工表面性能进行了研究。研究结果表明，混粉电火花镜面加工不但能够显著降低加工表面粗糙度值，而且能够提高加工表面的耐磨性、耐蚀性和表层显微硬度。 |

| Abstract: |
| The surface characteristics of 8407 steel machined by a salf-mase mirror EDM equipment using mixed dielectric powders are examined. It is proved that mirror EDM with mixed dielectric powders can not only decrease the surface roughness, but also improve the surface abradability, corrosion-resistance and micro- hardness. |
