The invention discloses a high-hardness wear-resistant reticular bimetallic titanium-based composite material, which uses titanium or titanium alloy as the matrix, intermetallic compound particle phase self-generated in situ between the metal used for compounding and the matrix of titanium or titanium alloy, and used for compounding. The metals are sequentially distributed on the surface of the titanium or titanium alloy matrix in the form of a ring, forming a network structure bimetallic titanium matrix composite material; the invention also discloses a preparation of a high hardness wear-resistant network structure bimetallic titanium matrix composite material The method comprises performing high-energy ball milling on matrix powder and composite metal powder processed by high-energy ball milling, and then sintering. The invention utilizes the good self-lubricating effect of the metal used for the composite and the distribution strengthening effect of the particle phase of the intermetallic compound to improve the anti-friction and wear performance and hardness of the bimetallic titanium-based composite material; Powder, without cleaning, sensitization and activation of raw materials, simple process, strong operability, suitable for large-scale industrialization. |
