摘　　要：Ti(C,N)基金属陶瓷凭借着其低成本高性能的优势,被视为硬质合金的理想升级替代品,拥有广阔的应用前景。然而,与硬质合金相比,由于金属陶瓷的强韧性,尤其是断裂韧性相对较低,其应用范围受到限制。因此,如何进一步提高金属陶瓷材料的强韧性对扩大其应用领域和应用规模具有十分重要的意义。本文总结了近年来提高Ti(C,N)基金属陶瓷强韧性的主要技术,综述了相关的研究进展及提高金属陶瓷强韧性的相关机理,简述了目前金属陶瓷强韧化技术存在的问题,并对未来发展趋势进行了展望。Ti(C,N)-based cermets are seen as an ideal alternative to carbide and have a wide range of applications due to their low cost and high performance.However,compared to cemented carbide,the range of application of cermets is still relatively limited due to their low strength and toughness,especially the toughness.Therefore,how to further improve the strength and toughness of cermets to expand its application field and application scale is of great importance.In this paper,the primary technologies for improving the strength and toughness of Ti(C,N)-based cermets are summarized,the related research progress and mechanisms of improving the strength and toughness of cermet are clarified,the remaining problems in the strengthening and toughening technologies of cemets are briefly described and the future development trend is also prospected.
