Abstract: A novel low-cost spherical titanium powder process, wire induction heating-gas atomization (WIGA), was proposed in the present work. The effects of the gas pressure, metal temperature and the feeding speed on the particle size of the tita-nium powder were studied. The results indicated that the powders were spherical with rare satellite particles on the surface, the satellite particles accounted for one percent. The average particle size of powders decreased and the producing efficiency of fine size powders increased with the increase of gas atomization pressure, melt temperature, or with the decrease of feeding speed. The optimum parameters were gas pressure of 4.0 MPa, metal melt temperature of 2 000 ℃ and wire-feed speed of 0.8 m/min. Under the optimized condition, the average particle size of titanium powder was 41.8 micrometers, powder morphology was spherical, and “satellite” powders rarely existed on the surface of particles.
