摘　　要：钛及钛合金材料因其密度低、比强度高、耐腐蚀性能好等优异特性,在航空航天、汽车和军事等领域具有广阔的应用前景。近10年来,以石墨烯为代表的碳纳米材料由于具有超高的力学特性和独特的二维结构,广泛用作钛或钛合金基体的增强体。然而,纳米碳源的团聚现象以及严重的界面反应使纳米碳强化钛基复合材料的力学性能提升有限。随着对纳米碳强化钛基复合材料制备方法和工艺的深入探索,在其界面-组织-性能关系和强化机制等方面取得了一系列研究进展。在纳米碳强化钛基复合材料的制备过程中,必须从各个方面(如工艺特点、适用范围和应用要求等)衡量,选择合适的制备工艺,并通过界面结构设计优化来进一步改善基体组织,提高钛基复合材料力学性能。因此,系统性介绍近年来纳米碳强化钛基复合材料的制备工艺和纳米碳材料的表面改性及其应用,并对纳米碳强化钛基复合材料的界面结构调控和强化机制进行分析讨论,指出现阶段其制备、性能优化等方面存在的问题,并对其未来发展趋势进行展望。以期对以后纳米碳强化钛基复合材料的发展和应用提供一定的指导和借鉴。Titanium and titanium alloy materials have broad application prospects in aerospace,automotive and military fields due to their low density,high specific strength,good corrosion resistance etc.In the past decade,carbon nanomaterials(such as graphene)have been widely used as a kind of reinforcement for titanium or titanium alloy matrix owing to their ultra-high mechanical properties and unique two-dimensional structure.However,the agglomeration of nano-carbon sources and severe interfacial reactions often lead to the trade-off of strength and ductility of titanium matrix composites(TMCs).With the in-depth study of the preparation technology and process of Ti matrix composites reinforced with carbon nanomaterials,a series of research progress has been adopted in the interface-microstructure-performance relationship and strengthening mechanism of carbon nanomaterials reinforced TMCs.In the fabrication process of TMCs,it is necessary to select the appropriate preparation process from various aspects(including process characteristics,application scope and application requirements etc.),and further optimize the microstructure of TMCs and improve the mechanical properties of TMCs through the optimization design of interfacial structure.Therefore,this work systematically introduces the preparation process,surface modification and application of carbon nanomaterials reinforced TMCs in recent years,and discusses the interface structure regulation and strengthening mechanism of carbon nanomaterials reinforced TMCs.Finally,the existing problems are pointed out and the future development trend of carbonaceous nanomaterial reinforced carbon nanomaterials reinforced TMCs is prospected.It provides some guidance and reference for the development and application of carbonaceous nanomaterial/Ti composites in the future.
