A Design Study in Nickel-Based Superalloy Castings-- Combustor Floatwall Panel

Lost Foam Casting

The lost foam process has the capability to produce the floatwall panels in the size and number required and has an advantage in not requiring a dewaxing step.

But the lost foam casting process does not have the capability to:

  • Produce the thin walls or fine pins of the panels
  • Meet the desired tolerance for the threads and flanges on the mounting studs.
