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
