Adhesive-free polycrystalline diamond material and preparation method thereof
The invention discloses an adhesive-free polycrystalline diamond material. The material is prepared from the following raw materials: 50-100% of diamond micro-powder and 0-50% of non-diamond carbon powder, wherein the non-diamond carbon comprises graphite, amorphous carbon, carbon nanotubes, nano onion carbon, graphene and C60. According to the preparation method of the polycrystalline diamond material, 50-100% of the diamond micro-powder and 0-50% of the non-diamond carbon powder are used as raw materials, and a polycrystalline diamond material finished product is prepared through high-temperature high-pressure sintering. The non-carbon component mass ratio of the polycrystalline diamond material is lower than 1%, and the polycrystalline diamond material has extremely high hardness, extremely high wear resistance and extremely high thermal stability and is applied to manufacturing and preparing drilling teeth for oil and gas drilling and tools for machining.
本发明公开了一种无粘结剂多晶金刚石材料，制备原料包括50％～100％的金刚石微粉，0～50％的非金刚石碳粉；所述非金刚石碳包括石墨、无定型碳、碳纳米管、纳米洋葱碳、石墨烯、C60。上述无粘结剂多晶金刚石材料的制备方法，以50％～100％的金刚石微粉和0～50％的非金刚石碳粉为原料经高温高压烧结制备获得无粘结剂多晶金刚石材料成品。上述无粘结剂多晶金刚石材料非碳成分质量比低于1％，具有极高硬度、极高耐磨性及高热稳定性，应用于制作制备油气钻探的钻齿以及机械加工用刀具。
