Propose a high-performance engineering materials and multi-functional requirements

The rapid development of modern science and technology, engineering materials made ​​for high performance and multi-functional requirements, the target material needs in a complex and sometimes was almost harsh working environment, thus requiring materials  Polycrystalline diamond  workers in the design of materials to an overall grasp and global considerations. Doped material modification as an effective method is widely used in carbon materials research and industrial production among. cutting tools silicon doped graphite materials, which can be overcome silicon carbide and graphite materials in some performance deficiencies, both excellent performance of both, is attracting attention. It retains the self-lubricating graphite materials, electrical conductivity, thermal conductivity and thermal shock resistance, but also has silicon carbide oxidation resistance, wear resistance and at ambient and elevated temperatures of liquid and gaseous corrosive media advantages of working long hours It is an ideal engineering material.
