| 摘 要： | 采用脉冲紫外激光（XeCl，308nm）表面消融预处理方法以硬质合金为衬底制备了金刚石涂层刀具。利用压痕法对涂层结合强度进行了测试，得到了最佳预处理工艺条件。采用碳化硅增强铝合金材料对制备的金刚石涂层刀具进行了实际切削性能实验。实验结果表明:脉冲紫外激光表面消融预处理方法的采用对刀具的金刚石薄膜涂层附着强度的提高有很大的帮助。

| Abstract: | Electromagnetic field theory and electron motion conservation equations are used to derive numerical model of transverse space-charge flow and magnetically insulated critical condition in plane and cylinder transmission lines. Through numerical simulation, this paper discusses discussed the influence of the voltage and the geometrical parameters on the transverse space charge flow and magnetically insulated performances. |
