The invention belongs to the technical field of medical application, and discloses additive manufacturing orthopedic tantalum metal, a preparation method and application. A laser melting or electron beam technology is adopted for machining and forming, and production parameters of powder performance, laser melting parameters, equipment stability, powder laying quality, printing precision and oxygen contents are optimized. Hot isostatic pressing (HIP)/heat treatment (HT) is carried out on a formed part, then surface treatment is carried out, and a high-compactness and high-performance formed part can be obtained. The high-compactness and high-performance tantalum metal is provided and has stable and reliable mechanical performance after being implanted into a human body, in-vivo complicated environment and mechanical requirements are met, and different medical application scene requirements can be met in combination with subsequent surface treatment.

Example Embodiment

[0033] In order to make the objectives, technical solutions and advantages of the present invention, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.
[0034] For the problems present in the prior art, the present invention provides a method for producing an orthopedic tantalum metal, which will be described in detail below with reference to the accompanying drawings.
[0035] Such as figure 1 As shown, the preparation method of the addition of the additive manufactured bone tantalum metal according to an embodiment of the present invention includes the following steps:
[0036] Step 1, using laser melting or electron beam process to form a tantalum metal powder;
[0037] Step II. Optimize the production parameters of powder, laser melting parameters, equipment stability, laying quality, printing accuracy, oxygen content; laser power 100-1000W. Oxygen content <100 ppm;
[0038] Step 3, the molding parts are used to use the scene demand according to the material to use the heat treatment or hot isothermal treatment, and the surface treatment is performed, and highly dense, high-performance molded parts. The temperature is 1600 ~ 2000 degrees Celsius; the working pressure is 50 ~ 200MPa, and time 2-4 hours. In step three, the temperature in the heat treatment is 1950 degrees Celsius, 200 MPa, 2 hours.
[0039] The temperature in the surface treatment is 1750 degrees Celsius, 200 MPa, 2 hours. S101, using laser melting or electron beam process to form tantalum metal powder;
[0040] The present invention provides a additive material to produce orthopedic tantalum metal. Tantalum metal powder 45-75 um by adding materials.
[0041] Tantalum metal impurity composition ingredient (PPM)
[0042] H N O C FE Ni Cr NA K CA Mg Si W <10
[0043] The present invention will be further described below in conjunction with specific experimental data.
[0044] figure 2 It is a laser molten tantalum microgram, which can be seen that there are a large amount of distribution of spots and block defects.
[0045] image 3 After the manufacture of tantalum metal, heat isometric 1750 degrees, 200 MPa, 2 hours, and the spots in the picture, and the block defect is obviously eliminated.
[0046] Figure 4 After the production of tantalum metal, heat isometric 1950 degrees, 200 MPa, 2 hours, and the spots in the picture, the block defect is basically eliminated, and the material is higher than the slightly low treatment temperature (1750 degree) material.
