The invention belongs to the technical field of powder metallurgy composite materials, and particularly relates to a layered gradient Ti-Ti-based composite material and a preparation method and application thereof. The material comprises a substrate layer and a composite reinforcing layer, and the volume ratio of the substrate layer to the composite reinforcing layer is (6-10): 1; the substrate layer is a titanium or titanium alloy layer; the composite reinforcement layer comprises the following components: matrix titanium, an intermediate alloy B and a particle reinforcement body C, wherein the intermediate alloy B is selected from one or more of an Al-V alloy, an Al-Mo alloy and an Al-Sn alloy; and the particle reinforcement C is selected from one or more of TiB2, B4C, SiC and Al2O3. And by adding the particle reinforcement, the wear resistance of the titanium-based composite material is effectively improved, so that the ground plane part of the obtained material has excellent wear resistance, and the application range is wide. The particle reinforcement titanium-based composite material is combined with titanium or titanium alloy through the two-stage pressing forming process, the manufacturing process is simple in flow, and industrial production can be achieved.
