1. Thermal Spray Powders

2. Special Capabilities / Powder Mfg. Gas atomization –MCrAlYs, metal alloys, superalloys & braze powders Sintering –Carbide and ceramic powders Casting –Carbide and ceramic powders Composite/Agglomerate –TBC, metal alloy & carbide powders Physical Blending –Cr2C3-NiCr & others APT Technology –Chromium and tungsten based

3. Atomization Prepare raw materials Vacuum induction melt Pour molten metal Break molten metal into droplets and rapidly solidify (atomize) Collect powder Atomization “Close-up” Melt Chamber Induction Furnace Collection Bucket

4. VIGA 250

5. Sintering Procedure –Mix raw materials –Place in furnace –Program furnace cycle (heating & cooling) –Sinter –Breakdown sintered mass Composition A Composition B Composition C to cause to become a coherent mass by heating without melting Sinter:

6. Sintering

7. Cast & Crush Prepare raw materials Heat raw materials until molten (alloy) Cast into crucible Crush solidified mass High Electric Current Melting

8. Composite / Agglomerated Mix raw materials into a liquid chemical suspension “Atomize” or drive-off binders to form agglomerates Collect dry agglomerated powder Composition A Composition B Organic Binder Composition B Composition A
