[0017] Example 1
[0018] Figure 1 is a process flow chart of the preparation of porous titanium artificial bone by sintering titanium fiber three-dimensional weaving technology and the preparation of bioceramic coating on the surface of porous titanium artificial bone. A titanium metal fiber wire with a diameter of 0.2mm is woven in an orthogonal structure. First, in a circular area with a diameter of 15mm, the titanium wire is woven into a uniform and parallel horizontal arrangement structure, and the distance between each arrangement is 1mm. , and then the titanium wire is woven back and forth from the parallel lines just woven in the longitudinal direction, and a group of uniform and mutually parallel arrangement structures are also formed in the longitudinal direction. The spacing is also 1mm, and the horizontal and vertical titanium wires are arranged in parallel. The structures are staggered vertically with each other. On the basis of this layer, weave the second layer ...

[0020] Example 2
[0021] The orthogonal porous structure titanium mesh frame was constructed by the three-dimensional weaving method. A titanium metal fiber wire with a diameter of 0.6 mm was woven according to the orthogonal structure. First, the titanium wire was woven into a uniform transverse direction in a circular area with a diameter of 20 mm. , parallel arrangement structure, the distance between each arrangement is 0.5mm, and then the titanium wire is woven back and forth from the parallel line just woven in the longitudinal direction, and a group of uniform and parallel arrangement structure is also formed in the longitudinal direction. The spacing is also 0.5mm, and the horizontal and vertical titanium wires are arranged in parallel and staggered vertically. On the basis of this layer, the second layer is woven according to the same method and steps until a porous titanium wire with a height of 30mm is formed. The wire mesh frame structure is then placed in the mol...

[0023] Example 3
[0024] The three-dimensional weaving method was used to construct a titanium mesh frame with an orthogonal porous structure. A titanium metal fiber wire with a diameter of 0.4 mm was woven in an orthogonal structure. First, the titanium wire was woven into a uniform transverse direction in a circular area with a diameter of 10 mm. , parallel arrangement structure, the distance between each arrangement is 1.5mm, and then the titanium wire is woven back and forth from the parallel line just woven in the longitudinal direction, and a group of uniform and parallel arrangement structure is also formed in the longitudinal direction. The spacing is also 1.5mm, and the horizontal and vertical titanium wires are arranged in parallel and staggered vertically. On the basis of this layer, weave the second layer according to the same method and steps until a porous titanium wire with a height of 20mm is formed. The wire mesh frame structure is then placed in the mold, an...
