Abstract: Diamond/Cu composite materials combine the advantages of diamond and Cu, and have excellent properties such as high hardness, high thermal conductivity, low coefficient of thermal expansion, and good wear resistance. They are one of the research focuses in the field of metal-based composite materials. The preparation of diamond/Cu composite materials was first carried out using high-temperature and high-pressure sintering processes, which can effectively avoid the negative effects of graphitization of diamond particles. With the continuous development of industry and technology, various preparation processes have emerged in the industry. Adding titanium metal to composite materials can improve the main phase content, microstructure, interface structure and other structural characteristics inside diamond/Cu composite materials, the key factors affecting their overall performance. A systematic review is conducted on the domestic and international technologies for the preparation of diamond/Cu composite materials. The influence of titanium metal on the thermal conductivity, thermal expansion properties, mechanical properties, microstructure, and interface reaction mechanism of diamond/Cu composite materials is elucidated. The current research problems in diamond/Cu composite materials are analyzed, and the future development direction of composite materials is discussed.

Key words: diamond/Cu composite material, titanium metal, interface structure, thermal conductivity
