The invention discloses a method for 3D printing an in-situ self-generated multi-level nano-ceramic phase-strengthened titanium alloy bone implant, which comprises the following process steps: bone implant data model construction and post-processing; titanium alloy, boron and carbon nanotube composite Optimum design and preparation of the powder; mixing high-purity argon and nitrogen gas into the forming cavity of the laser 3D printing equipment to form a titanium alloy bone implant; cleaning, sterilizing, and drying before packaging. Based on the advanced laser 3D printing technology and the excellent performance of the in-situ self-generated nano-ceramic phase, the invention forms a titanium alloy bone implant with a uniformly dispersed and strengthened multi-level nano-ceramic reinforcing phase, effectively improves its comprehensive performance, and realizes high-performance artificial titanium Fabrication of Alloy Bone Implants. The process method of the invention is simple, has excellent comprehensive performance, has good economic value and broad market prospect. |
