The invention discloses a gradient titanium-magnesium composite material implant for inducing bone growth and a forming method thereof, and belongs to the field of manufacturing functional bone implants. The titanium alloy porous structure implant body formed by selective laser melting is extruded and filled with slow-release magnesium alloy and nano-hydroxyapatite composite material with osteo-induced growth to form a gradient titanium-magnesium composite implant. The invention is implanted under the joint action of the slow release of magnesium alloy and the induction of hydroxyapatite, and can easily induce the controllable growth of bones, and has good market prospect and application value. |
