Embodiment 1
[0039] Example 1, Ti6Al4V powder with an average particle size of 20 μm, a purity of 4N, a spheroidization rate of 90%, an oxygen content of less than 2000 ppm, and a nitrogen content of less than 500 ppm. The main parameters of the preparation process are: the purity of the Ti6Al4V furnace charge is 2N -3N, system vacuum 6×10 -4 MPa, the oxygen content of the system is less than 1ppm, the power supply is 200Kw, the supersonic high-pressure argon pressure is 5.23MPa, the vibration frequency is 85HKz, and the argon pressure of the two-stage cooling device is 0.6MPa.
Embodiment 2
[0040] Example 2, the average particle size is 20 μm, the purity is 4N, the spheroidization rate is 90%, the oxygen content is lower than 1800ppm, and the pure powder with nitrogen content is lower than 300ppm. The main parameters of the preparation process are: the purity of the pure titanium charge is at 2N-3N, system vacuum 6×10 -5 MPa, the oxygen content of the system is less than 1ppm, the power supply is 200Kw, the supersonic high-pressure argon pressure is 5.23MPa, the vibration frequency is 85HKz, and the argon pressure of the two-stage cooling device is 0.6MPa.
[0041] The titanium-based powder material is prepared by a vacuum magnetic levitation smelting powder-making device, which improves the purity of the titanium-based powder material, reduces the oxygen content and nitrogen content of the material, and has a high powder spheroidization rate and good sphericity. It can be well used in the traditional powder metallurgy industry and the emerging laser 3D printing ...
