| 摘 要： | 本文通过建立整体硬质合金立铣刀上制备CVD金刚石涂层时CVD沉积系统流场的三维模型,研究了进气口分布对该系统流场均匀性的影响,优化了进气口的分布;在仿真的基础上开展了整体硬质合金立铣刀上制备CVD金刚石涂层的验证实验,采用SEM和Raman对制备的CVD金刚石涂层进行了分析测试.结果表明:优化后的流场可以用于制备高质量的CVD金刚石涂层,且批量制备出的在衬底不同位置上的铣刀表面CVD金刚石涂层的质量均匀一致.

| Abstract: | A three-dimensional finite element model of diamond coating on cemented carbide milling cutter in a CVD system was created and the gas flow field was simulated.It shows that proper distribution of inlets is a particularly important factor for obtaining a uniform gas flow field.On this basis,some CVD diamond coated cemented carbide end mills were prepared in this system as a verification.The coated milling cutters were analyzed by SEM and Raman.The results show that the selected distribution of inlets was ab... |
