Abstract: Disclosed are a wear-resistant gradient interface complex-phase reinforced titanium alloy material and a preparation method therefor. The material comprises a titanium alloy matrix and a TiC ceramic reinforcement phase and a TiN ceramic enhancement phase dispersed within the titanium alloy matrix. The titanium alloy matrix is a titanium-aluminum-molybdenum-vanadium-zirconium alloy, wherein the aluminum content is 5.5-6.5 wt.%, the zirconium content is 1.6-2.0 wt.%, the molybdenum content is 1.0-1.5 wt.%, the vanadium content is 1.0-1.8 wt.%, and the balance is Ti. The TiC ceramic reinforcement phase accounts for 10-15 wt.% of the total mass of the alloy material, and the TiN ceramic reinforcement phase accounts for 10-15 wt.% of the total mass of the alloy material. A titanium-aluminum-molybdenum-vanadium-zirconium alloy powder and micron-sized TiC and TiN powders are used as raw materials, and a ceramic-reinforced titanium-based composite material is prepared by means of a selective laser melting technology after ball milling and powder mixing. A TiC-Ti(C,N)-TiN gradient interface structure is formed, thus improving the interface bonding between the ceramic reinforcement phases and the titanium matrix, reducing the tendency of the composite material to crack due to stress concentration during the melt rapid condensation, reducing cracks in a formed titanium-based composite material, and improving the forming quality and the mechanical properties thereof.
