Refractory metal core for cast seal slots in turbine vane shrouds

摘要

A process for casting a turbine engine component is provided. The process comprises the steps of placing a refractory core assembly (30) comprising two intersecting plates (32, 34) in a die (38), encapsulating the refractory core assembly (30) in a wax pattern (40) having the form of the turbine engine component, forming a ceramic shell mold (42) about the wax pattern (40), removing the wax pattern (40), and pouring molten material into the ceramic shell mold (42) to form the turbine engine component.
