Powder Metallurgy

Powder metallurgy begins as a metal or ceramic in a powdered form, which is then consolidated in a variety of different ways to produce high quality parts.

Powder metallurgy has many advantages over the conventional engineering process; with a highlight being that the process now allows products to be made that would not have previously been possible. 

 
  • Production waste is eliminated as precise shapes and sizes can be formed without many manufacturing steps;
  • The ability to reduce manufacturing time, which produces a more cost effective product;
  • Highly complex components are able to be produced with ease;
  • A flexible process, which can custom produce alloys with multiple alloying elements at no significant extra cost.
The industry applications are limitless; with titanium being used in the production of hip joints and a wide range of medical implants, cogs, nozzles, jet engine and aircraft parts, sports equipment, and compressor blades.
A chemical or mechanical process is used to produce titanium alloy powder, which is then consolidated into a desired shape or high performance coating. 
 

Consolidation methods include:

  • Compacting/sintering;
  • Injection moulding;
  • Spray forming;
  • Laser deposition/laser sintering;
  • Hot isostatic pressing/cold isostatic pressing;
  • Foam structures;
  • Screen printing;
  • Coating;
  • Hot working processes i.e. extrusion, rolling and forging.
