Granted patent CN116511484B proposes a low-cost titanium-based powder preparation method: using two near-spherical titanium-based powders with different median particle sizes as raw materials, a uniform bimodal particle size distribution powder is obtained through wet mixing in suspension and rotary debinding during furnace processing. The particle size grading is used to increase the apparent density and flowability of the powder, meeting the demand for low-cost, high-performance titanium parts in aerospace and other fields.
