金刚石复合涂层、具有该复合涂层的梯度超细硬质合金刀具及其制备方法
摘要：
一种金刚石复合涂层、具有金刚石复合涂层的梯度超细硬质合金刀具及其制备方法。合金刀具由刀具基体和金刚石复合涂层构成。刀具基体设置有正常组织层、富钴过渡层和贫钴富立方相层。金刚石复合涂层包括作为过渡层的Ti‑Al‑Si‑Cr合金层和作为功能层的金刚石层。本发明具有该金刚石复合涂层的梯度超细硬质合金刀具，其刀具基体与金刚石复合涂层结合性好，整体刀具具有良好的耐磨耐温性能，强度高、抗冲击性能优良。金刚石复合涂层，其与刀具基体结合性良好，复合涂层的涂层之间附着力良好，其耐高温性、耐腐蚀性、耐磨性良好。
摘要（英）：

A diamond composite coating, a graded structure ultrafine hard alloy cutting tool with the diamond composite coating, and a method for manufacturing same. The alloy cutting tool comprises a cutting tool base body and the diamond composite coating. The cutting tool base body is provided with a normal organization layer, a cobalt-rich transition layer, and a cobalt-poor cube-rich phase layer. The diamond composite coating comprises a Ti-Al-Si-Cr alloy layer as a transition layer and a diamond layer as a functional layer. The cutting tool base body of the graded structure ultrafine hard alloy cutting tool with the diamond composite coating disclosed in the invention exhibits good adhesion to the diamond composite coating. The entire cutting tool has good resistance against abrasion and high temperature, high strength and excellent shock resistance. The diamond composite coating has good adhesion with the cutting tool base body, good layer-to-layer adhesion within the composite coating, and good resistance against high temperatures, corrosion, and abrasion.
