Embodiment 1
[0027] Weigh 12000 g of Ti64 titanium alloy (Ti6Al4V) powder, D50=12-14 microns; 2048 g of metal vanadium powder, 500 mesh; 16 g of stearic acid, powder particle size of 0.2-0.3 mm.
[0028] The above three kinds of powders were put into the mixing barrel and mixed thoroughly for 12 hours to obtain Ti518 powder.
[0029] Take 4250g of mixed Ti518 powder into the mixing chamber of the mixer, heat at 175°C for 10 minutes, then add 600g of copolymerized polyoxymethylene (9520), 125g of lubricant (PW) and 25g of BASF (B215) in turn, and continue After mixing for 30 minutes, during the mixing process, argon gas was introduced into the mixing chamber for protection under positive pressure, and the argon gas pressure was 1.2Mpa. After the mixing is completed, the pellets are diced and cooled to obtain β-type titanium alloy feedstock Ti518 (Ti5Al18V).
Embodiment 2
[0031] Take 4500g of Ti518 powder mixed in Example 1 and add it to the mixing chamber of the mixer, heat at 175°C for 10 minutes, then add 400g of copolymerized polyoxymethylene (9520), 95g of lubricant (PW) and BASF (B215) in turn. ) 5g, and continued to mix for 30 minutes. During the mixing process, argon was introduced into the mixing chamber for protection under positive pressure, and the argon pressure was 1.2Mpa. After the mixing is completed, the pellets are diced and cooled to obtain β-type titanium alloy feedstock Ti518 (Ti5Al18V).
Embodiment 3
[0033] Take 4435g of Ti518 powder mixed in Example 1 into the mixing chamber of the mixer, heat at 175 ° C for 10 minutes, then add 500g of copolymerized polyoxymethylene (9520), 50g of lubricant (PW) and BASF (B215 ) 15g, and continued to mix for 30 minutes. During the mixing process, argon was introduced into the mixing chamber for protection under positive pressure, and the argon pressure was 1.2Mpa. After the mixing is completed, the pellets are diced and cooled to obtain β-type titanium alloy feedstock Ti518 (Ti5Al18V).
[0034] The β-type titanium alloys prepared in Examples 1-3 were taken as feeding materials, and three groups of β-type titanium alloy tensile workpieces were obtained by injection molding respectively.
[0035] Place the β-type titanium alloy drawn workpiece on a high-purity zirconia ceramic plate, and then put it into a degreasing furnace for degreasing. Set degreasing temperature 100℃, nitrogen flow 5m 3 / h, the acid amount is 200ml / h, after the degr...
