Abstract

A process for forming an airfoil portion (42) of a turbine engine component, such as a turbine blade, is described. The process comprises the steps of placing a ceramic core (14) having a configuration of a passageway (15) to be formed in the airfoil portion (42) within a mold (80), attaching a refractory metal core element (10) to the ceramic core (14) to stabilize a tip region (12) of the ceramic core (14), and casting the airfoil portion (42).
