The invention discloses a preparation method of particle-reinforced wearable porous titanium. The preparation method comprises the following steps of: S1, sufficiently and uniformly mixing the titanium powder and the wearable material particle; S2, adding a pore-forming agent to the powder mixture, and sufficiently and uniformly mixing; and S3, pressing and forming; S4, heating up the pressed powder blank in a heating furnace, removing the pore-forming agent, and placing in a vacuum sintering furnace for sintering to obtain the particle-reinforced wearable porous titanium. The preparation method of the particle-reinforced wearable porous titanium has the beneficial effects as follows: the process is simple, the device requirement is low, the processing cost is lowered and the operation is convenient; the porosity and the pore size can be controllable; the added pore-forming agent is low in cost, and the pore of the porous titanium can be controlled well; the added wearable hard particle has the characteristics of high melting point, high hardness, good antioxidant capacity, good lubricity and wear resistance and the like, so that the comprehensive performance of the porous titanium is improved well; the prepared porous titanium is uniform in pore distribution, good in wear and corrosion resistance, good in process controllability, simple and low in cost.
