Abstract
The present disclosure is directed to a refractory metal core for use in forming varying thickness microcircuits in turbine engine components, a process for forming the refractory metal core, and a process for forming the turbine engine components. The refractory metal core is used in the casting of a turbine engine component. The core is formed by a sheet of refractory metal material having a curved trailing edge portion integrally formed with a leading edge portion.
Claims19
A process for forming a turbine engine component comprising the steps of:
- providing a non-ceramic core formed predominantly from a refractory metal material;
- providing a mold having a shape of said turbine engine component;
- positioning only said non-ceramic core within said mold;
- introducing a molten metal material into said mold and allowing said molten metal material to solidify and form said turbine engine component;
- and
- removing said non-ceramic core from said solidified turbine engine component.
A process for forming a refractory metal core for use in a turbine engine component casting system comprising the steps of:
- providing a piece of refractory metal material having a substantially flat side;
- subjecting said piece of refractory metal material to an operation to alter a curvature in said refractory metal material and form a curved trailing edge portion;
- and
- fabricating said piece of refractory metal material to have different thicknesses in different portions.
