Thermal Spray Powders Special Capabilities Powder Mfg Gas

Thermal Spray Powders

Special Capabilities / Powder Mfg. • Gas atomization – MCr. Al. Ys, metal alloys, superalloys & braze powders • Sintering – Carbide and ceramic powders • Casting – Carbide and ceramic powders • Composite/Agglomerate – TBC, metal alloy & carbide powders • Physical Blending – Cr 2 C 3 -Ni. Cr & others • APT Technology – Chromium and tungsten based

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

VIGA 250

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

Sintering

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

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

Thermal Barrier Coatings

Physical Blends • Prepare raw materials (previously manufactured) • Blend
