To improve the hardness and wear resistance of titanium (Ti), it is proposed to introduce TiB₂ hard phase into pure Ti to accurately control the reaction process of the two components based on the discharge plasma sintering (SPS) technique, and to construct a TiB₂-TiB-Ti "hard-core-strong-interface" structure in Ti matrix that inherits the diffusion path of B element. Finally, a high hardness of 863.5 HV₅ at room temperature and 720.9 HV₅ at 400 ℃ is obtained with the addition of 40% TiB₂, 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 strain of about 11.7% at 400 ℃. 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.
