| 中文摘要:在仿生高效耐磨理论的指导下，以鼹鼠爪趾为仿生原型，引入了其经长期进化而具有的高效、耐磨的特性。选用CVD多晶金刚石为切削齿的切削单元，采用真空热压烧结工艺制备仿生高效切削齿，并将其与常规PDC齿、仿生PDC齿的耐磨性和切削效率进行对比试验，结果显示：仿生高效切削齿的耐磨性较常规PDC齿提高23%；切削效率较常规PDC齿提高1.49倍，较仿生PDC齿提高48%。初步证明了仿生高效切削齿工艺的可行性，为下一步高效切削钻头的研究奠定了坚实的基础。 |

| Abstract:Under the guidance of the bionic theory, taking mole claws as bionic prototype, the high efficiency and wear resistance properties obtained from long-term evolution are introduced. CVD polycrystalline diamond cutters were selected as cutting unit and efficient bionic cutting teeth were prepared with vacuum hot pressing sintering process. By the contrast tests, the results reveal that the wear resistance of efficient bionic cutting teeth is increased by 23% compared with the conventional PDC teeth; the cutting efficiency is 1.49 times that of the conventional PDC teeth and 48% higher than bionic PDC teeth. It preliminarily proves the feasibility of the process of efficient bionic cutting teeth, which lays a solid foundation for further study on efficient cutting bit. |
