Embodiment 1
[0035] The raw material components of a biomedical β-titanium alloy are as follows in terms of mass percentage: Mo: 11.25%; Fe: 1.75%; Zr: 5.82%; Ta: 0.21%; the balance is Ti.
[0036] The preparation method is as follows:
[0037] (1) take preparation raw material, comprise Zr, Mo, Ta, Fe, Ti and very small amount of unavoidable C and Si, each component content is as shown in table 1, and each component purity is 99.2wt%; Each raw material After being melted in a crucible, it is forged into a rod with a diameter of 29.2 mm and a length of 150 mm for preparation of spherical powder.
[0038] (2) Use the plasma rotating electrode atomization method to make powder, heat it to 1700°C in a vacuum environment, obtain the molten alloy after smelting for 65 minutes, and use high-purity argon gas for spray granulation to collect alloy powder with a particle size of 12-75 μm. The key The parameters and detailed steps of the powder making process are as follows: firstly vacuum the insi...
