摘要
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.
Abstract
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.
