纳 米碳 强 化 钛 基复 合 材 料界 面 结 构与 性 能 优化 研 究 进展

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.
