| 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: | In this paper, tool's diamond coating are fabricated on tungsten carbide by pulsed UV laser surface pretreatment. The adhesion of diamond coatings under different laser pretreatment conditions are evaluated using indentation test. The optimum laser pretreatment conditions is obtained. Diamond coating tools are actually tested by machining of SiC Al composite materials. The adhesion of diamond coating to tungsten carbide was greatly improved by the pulsed UV laser substrate pretreatment. |
