扫码查看
TiB2陶瓷具有高熔点、高硬度、高耐磨以及优异的导电性能和高温抗氧化性能,被广泛应用于航空航天、机械制造、金属冶炼、电子信息等领域.TiB2陶瓷的相对密度低、加工难度大,难以满足高端制造的应用需求,而通过掺杂改性、添加烧结助剂、优化烧结工艺等方式可以促进TiB2陶瓷的致密化,大幅提升其综合力学性能.本文综述了高性能TiB2陶瓷在成分设计、烧结工艺等方面的研究进展,并阐述了其在精密工具、防弹装甲、电解阴极等方面的应用前景.
Research progress and applications on TiB2 ceramic
With high melting point,high hardness,high thermal conductivity,excellent electrical conductivity,and high temperature oxidation resistance,the TiB2 ceramic has been applied in the fields of aerospace,machinery manufacturing,metal smelting,electronic information,and so on.However,the high-end manufacturing application of TiB2 ceramic has been limited by the low relative density and the difficulty of machine-processing.The densification of TiB2 ceramic could be improved by doping modification,adding sintering additives,optimizing sintering process,and so on,which significantly improves the mechanical properties.The research progress of high-performance TiB2 ceramic in terms of composition design and sintering processing was reviewed in this paper.The applications of TiB2 ceramic were also prospected on precision tools,bulletproof armor,and cathode tools.
