| titleOfInvention | Porous metal material with closed pore structure and preparation method thereof |
| abstract | The invention provides a porous metal material with a closed pore structure and a preparation method thereof, and relates to the technical field of porous metal material preparation. The invention uses SiO 2 After the sensitization treatment of the microsphere powder, chemical plating is carried out on the powder, and SiO is carried out 2 Forming a metal layer on the surface of the microsphere to obtain the composite SiO 2 Microsphere powder; the composite SiO 2 And soaking the microsphere powder in HF solution, mixing the obtained hollow metal spherical shell with metal powder, and sintering to obtain the porous metal material with a closed pore structure. The invention can conveniently obtain the porous metal material with the closed pore structure and can control SiO 2 The diameter of the microsphere powder and the mass ratio of the hollow metal spherical shell to the metal powder conveniently regulate and control the aperture and porosity of the porous metal material, and ensure uniform aperture distribution; and the porous metal materials with different macroscopic appearances are obtained by designing moulds with different shapes in the sintering process. |
