There are still many problems in the development of MIM of titanium and titanium alloys:

  Low oxygen spherical titanium powder price is high, oxygen pollution makes nano titanium powder difficult to obtain;

  The selection and removal process of binder, currently the most practical is EBS wax, but need vacuum or argon environment to remove, high cost;

  Gap element removal, etc Low oxygen fine-grained spherical titanium powder preparation of low cost is the main development direction of titanium and titanium alloy powder. 

The aerosol preparation technology of titanium powder particle size small spherical degree is high Oxygen content is low, have the ability to mass production and low cost, is the production of high performance the main method of spherical titanium and alloy powder At the same time, the development of a new and efficient binder system for titanium alloy MIM to optimize mixing and degreasing sintering process and injection parameters is the key to prepare low-cost and high-performance titanium alloy injection molding parts.
