一种聚晶金刚石复合片
摘要：
本发明公开了一种聚晶金刚石复合片，本发明所提供的聚晶金刚石复合片不是将聚晶金刚石层和硬质合金层直接结合，而是在两层之间增加过渡层。过渡层可以是单层也可以是多层，根据不同的目的，过渡层的组成成分也有所不同。由于在聚晶金刚石层和硬质合金层之间增加了过渡层，不仅能改善聚晶金刚石复合片的界面结合情况，减少界面应力，还能同步提高聚晶金刚石复合片的耐磨性和抗冲击韧性。
摘要（英）：

The invention discloses a polycrystalline diamond composite sheet. In the polycrystalline diamond composite sheet provided by the invention, a polycrystalline diamond layer is not directly combined with a hard alloy layer, but a transitional layer is added between the polycrystalline diamond layer and the hard alloy layer. The transitional layer can be a single layer or formed by multiple layers,and the compositions of the transitional layer are different from one another according to different purposes. The transitional layer is added between the polycrystalline diamond layer and the hard alloy layer, so that the interface combination condition of the polycrystalline diamond composite sheet can be improved, interfacial stress can be reduced, and the abrasion resistance and the impact-resistant toughness of the polycrystalline diamond composite sheet can be synchronously improved.
