A preparation method for laser 3D printing metal-ceramic composite powder |
| abstract |
The invention discloses a preparation method for laser 3D printing metal-ceramic composite material powder, and belongs to the field of powder material preparation for laser 3D printing. In the present invention, pure Ti powder and pure B 4 C powder particles are coated (or bonded) in a mass ratio of 2.6:1 by a physical method, and are successively dried and ball-milled to obtain a Ti/B 4 C composite powder material. Then the powder material and AlSi10Mg powder are added to a ball mill for vacuum ball milling, and finally a uniformly mixed powder for laser 3D printing metal-ceramic composite materials is obtained; The technical problem that the phase cannot be synthesized increases the reaction rate of Ti and B 4 C particles during the laser 3D printing process, and increases the content of the ceramic reinforcing phase in the dual-phase composite material; the prepared composite powder can be used for laser near-net shaping or High-energy beam 3D printing processes such as selective laser melting. |
