Presentation Transcript

  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 Melt Chamber • 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

  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 HEAT Sinter: to cause to become a coherent mass by heating without melting Composition C

  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 B Composition A Organic Binder Composition B Composition A

  9. Thermal Barrier Coatings

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