摘　　要：Ti(C,N)基金属陶瓷是由金属粘结相和陶瓷硬质相组成的复合材料,具有出色的硬度和韧性组合,在高速切削、表面精加工和耐磨部件等领域广泛应用。使用新型粘结相(金属间化合物、高熵合金、Fe基合金、Ni基合金)来代替传统的Ni、Co、Fe及其复合粘结相时,Ti(C,N)基金属陶瓷的力学性能、耐磨性能、耐腐蚀性能和高温抗氧化性能等均有改善,其使用寿命得以延长。本文综述了国内外采用不同新型粘结相制备的Ti(C,N)基金属陶瓷的显微组织、力学性能、耐磨性能、耐腐蚀性能及抗氧化性能等方面的研究进展,总结了新型粘结相提高金属陶瓷性能的机理,并在此基础上展望了Ti(C,N)基金属陶瓷新型粘结相的未来研究发展方向。Ti(C,N)-based cermets are composite materials composed of metal binder phase and ceramic hard phase.Due to the excellent combination of hardness and toughness,they are widely used in high-speed cutting,surface finishing processes and wear-resistant parts.When new binder phases(intermetallic compounds,high entropy alloys,Fe-based alloys,Ni-based alloys)are used to replace the traditional Ni,Co,Fe and their composite binders,the mechanical properties,wear resistance,corrosion resistance and high-temperature oxidation resistance of the Ti(C,N)-based cermets are improved,and their service life is increased.This paper summarizes the research progress of the Ti(C,N)-based cermets prepared with different new binder phases at home and abroad in the aspects of microstructure,mechanical properties,wear resistance,corrosion resistance and oxidation resistance,summarizes the mechanism of the new binder phase to improve the performance of the cermets,and on this basis,looks forward to the future research and development direction of the new binder phase of the Ti(C,N)-based cermets.
