Preparation method of peritectic titanium alloy powder

[0022] Example 1

[0023] A preparation method of peritectic titanium alloy powder, comprising the following steps:

[0024] S1. Wash the industrial pure titanium TA1 powder and TC4 alloy powder (the mass fraction of each component is: Al: 6.0%, V: 4.5%, other impurities ≤ 0.01%, and the balance is Ti) in vacuum with pure argon gas respectively;

[0025] S2. Put 60 parts by weight of TA1 powder into a vacuum sintering furnace, and the vacuum degree is 10 -3 Pa was filled with inert argon gas, then heated to 980°C, kept for 30min for microwave smelting, put in 5.5 parts by weight of La and mixed evenly, kept for 30min, cooled to 890°C, added 30 parts by weight of TC4 alloy powder, kept for 60min, placed in the abrasive tool Medium-cooled into an alloy rod with a diameter of 60mm and a length of 500mm;

[0026] S3. Use the rotating electrode atomization method to obtain spherical powder from the alloy rod:
