In order to improve the hardness and wear resistance of titanium (Ti), in this paper, it is proposed to introduce TiB2 hard phase into pure titanium (Ti), accurately control the reaction process of the two based on the discharge plasma sintering (SPS) technology, and construct a TiB2-TiB-Ti "hard-core-strong-interface" structure in Ti matrix that inherits the diffusion path of B elements. Finally, at 40% TiB2 addition, a high hardness of 863.5 HV5 at room temperature and 720.9 HV5 at 400℃ in the middle and high temperatures is obtained, which makes its friction performance better than that of commercial TC4 high-temperature titanium alloys under the same friction conditions in the temperature range from room temperature to 400℃. At the same time, thanks to its excellent bonding interface, the alloy also exhibits unique high-temperature and high-toughness properties, maintaining a high compressive strength of 1120 MPa and compression of more than 10% at 400℃. The design concept of this study is inspirational and useful. The design idea of this study is inspiring and universal, which is expected to provide a new method for the research and development of new medium-high-temperature and high-toughness wear-resistant titanium alloys, and to promote the application of related materials in aerospace field.
