Embodiment Construction
[0027] Step 1: Scan the skeletal tissue structure of the part of the human body that needs to be replaced with a CT scanning device, and establish a three-dimensional structural data model of the skeletal tissue structure of the part.
[0028] The second step: molar ratio of metal Ti powder, Mg particles, Si particles, Ca particles, Cu particles, Ag particles, Ni powder and Mo powder: (25-45): (15-30): (20-35 ): (5-10): (3-6): (5-15): (3-8): (0.1-0.5) After uniform mixing and preparation, the mixture is subjected to high-energy ball milling, Make the maximum spherical diameter not exceed 100nm to obtain ultrafine powder.
[0029] Add the modificator to the powder and preheat it by irradiation, continue to stir the mixed material within 30 minutes, and at the same time heat the temperature of the raw material to 150°C at a uniform speed, and keep it warm for later use. The stirring operation adopts magnetic stirring, and the preheating heat source is a radiation heat source. ...
