Embodiment 1
[0017] The porous titanium of this embodiment is connected between the cavity and the cavity, and the cavity is also connected with the outside world. The cavity diameter of the porous titanium is 300 μm-600 μm, and the porosity is 96.9%. The preparation method is as follows:
[0018] (1) Take titanium hydride powder with a particle size of 400nm-600nm, urea powder with a particle size of 400μm-750μm, and rare earth Y with a particle size of 50nm-80nm 2 o 3 Powder, rare earth neodymium powder with a particle size of 50nm-80nm, titanium hydride powder, urea powder, rare earth Y 2 o 3 powder, rare earth neodymium powder according to weight ratio titanium hydride powder: urea powder: rare earth Y 2 o 3 Powder: Rare earth neodymium powder is mixed in a ratio of 150:1280:1:4, stirred repeatedly in the mixer for 2 hours, and pressed into a green body under a pressure of 100MPa by cold isostatic pressing equipment.
[0019] (2) Put the green body into the graphite mold, put the m...
Embodiment 2
[0031]The cavity of the porous titanium in this embodiment is connected with the cavity, and the cavity of the porous titanium is also connected with the outside world. The diameter of the cavity of the porous titanium is 300 μm-600 μm, and the porosity is 86%. The preparation method is similar Example 1, wherein the porosity and pore size are controlled by urea content and particle size, and the same method is tested with reference to Example 1, and the energy absorbed per unit volume of the porous titanium in this example is 1.6×10 when the strain reaches 50%. -3 J / mm 3 , The ratio of open porosity to porosity is 99.2%.
[0032] The dog implantation test was carried out with reference to the same method as in Example 1, and the porous titanium was implanted into the frontal bone. The results showed that there were no defects such as cracks and damage in the porous titanium after the operation, and the bone tissue grew into 78% of the pore volume of the porous titanium 12 we...
Embodiment 3
[0034] The cavity of the porous titanium in this embodiment is connected with the cavity, and the cavity of the porous titanium is also connected with the outside world. The diameter of the cavity of the porous titanium is 300 μm-600 μm, and the porosity is 81%. The preparation method is similar Embodiment 1, wherein porosity and pore size are controlled by urea content and particle size.
[0035] With reference to the same method test in Example 1, the energy absorbed per unit volume of the porous titanium in this example is 1.05×10 when the strain reaches 50%. -2 J / mm 3 , The ratio of open porosity to porosity is 98.8%.
[0036] The dog implantation test was carried out with reference to the same method as in Example 1, and the porous titanium was implanted into the thoracic vertebrae. The results showed that there were no defects such as cracks and damage in the porous titanium after the operation, and the bone tissue grew into 80% of the pore volume of the porous titanium...
