| titleOfInvention | Magnesium or magnesium alloy-porous hydroxyapatite composite and preparation method thereof |
| abstract | The invention discloses a magnesium or magnesium alloy-porous hydroxyapatite composite and an extrusion casting preparation technology thereof. Aperture selection of the porous hydroxyapatite satisfies hundreds of micrometers required by clinical bone repair. In an extrusion casting process, smaller pressure is applied by a pressure head, so that a magnesium or magnesium alloy fusant is impregnated into pores of the porous hydroxyapatite, and then larger pressure is applied in a solidification process of the magnesium or magnesium alloy fusant, so that a structure of solidified magnesium or a solidified magnesium alloy is controlled. The magnesium or magnesium alloy-porous hydroxyapatite composite ensures double connectivity of the porous hydroxyapatite; magnesium or the magnesium alloy filled in the pores of the porous hydroxyapatite improves the strength; fracture of a structure of the porous hydroxyapatite is avoided; when the composite is used in the field of bone repair, the structure of the porous hydroxyapatite can still keep complete while magnesium or the magnesium alloy is degraded; bone cells can be induced to grow into multiple pores; and new bone forming is facilitated. |
