High-thermal-conductivity diamond composite material and preparation method thereof
The invention relates to the technical field of superhard material manufacturing, in particular to a high-thermal-conductivity diamond composite material and a preparation method thereof.The preparation method of the high-thermal-conductivity diamond composite material comprises the steps that diamond powder and a metal catalyst are mixed and then sintered, and a polycrystalline diamond composite material is obtained; performing soaking treatment on the polycrystalline diamond composite material by using the treating fluid to obtain a diamond porous material; and the diamond porous material is filled with heat conduction metal in an infiltration mode, and the high-heat-conduction diamond composite material is obtained through polishing treatment. The diamond porous material is filled with the heat-conducting metal in an infiltration mode, a concrete structure of the diamond and the heat-conducting metal is formed, and the concrete structure not only has heat conductivity close to that of the diamond, but also has high density; compared with a common diamond copper heat conduction material, the high-heat-conduction diamond composite material has higher hardness and heat conduction performance, the hardness is improved by 15-20 times on the original basis, and the heat conduction performance is improved by 2-3 times.
本发明涉及超硬材料制造技术领域，尤其涉及一种高导热金刚石复合材料及其制备方法，所述高导热金刚石复合材料的制备方法包括步骤：将金刚石粉与金属催化剂进行混合后，经烧结处理，得到聚晶金刚石复合材料；利用处理液对聚晶金刚石复合材料进行浸泡处理，得到金刚石多孔材料；将导热金属熔渗填充至金刚石多孔材料中，经打磨处理，得到高导热金刚石复合材料。本发明将导热金属熔渗填充至金刚石多孔材料中，形成金刚石与导热金属的混泥土结构，其不但具有接近金刚石的导热性，也具有较高的致密度；使得所述高导热金刚石复合材料比普通金刚石铜导热材料拥有更高的硬度及导热性能，硬度在原有基础上提升了15‑20倍，导热性能提升2～3倍。
