Chemical Vapor Deposition

Inside-out Processing

 

Using the layering capability inherent to CVD, Ultramet developed inside-out processing to facilitate the fabrication of complex functionally graded material systems.

 

Process

  • Fabricate mandrel that conforms to inner dimensions of final component.
  • Deposit desired material(s).
  • Remove mandrel to yield final part.

 

Advantages

  • Can deposit several materials to form a composite or lined structure
  • Can fabricate components with intricate inner geometries
  • Yields net-shape parts, requiring little or no postprocess machining
