摘　　要：本文简要介绍了化学气相法 (CVD)沉积金刚石薄膜原理和涂层模具的制备方法 ,以 WC- Co硬质合金紧压模为衬底 ,用热丝 CVD法沉积得到纳米金刚石复合涂层。检测了该涂层的 X射线衍射图、拉曼谱图和形貌。用该复合涂层技术制备得到的绞线紧压模在实际生产线上进行了初步的应用试验 ,模具工作寿命可提高达 10倍以上 ,绞线表面光洁度明显改善 ,取得了十分满意的结果。This paper presents the principle of the formation of diamond coating by the chemical vapour deposition (CVD) method and manufacture of coated dies. A nanometer diamond composite coating was formed on the surface of the WCCo hard alloy compacting die by the hot filament CVD method. The diagrams of the X ray diffraction and Raman spectrum were investigated. The initial application test of the dies made by the a.m. method shows that the die may have a service life that is 10 times longer and the surface of the stranded conductor has marked improved smoothness.
