Methods for making a turbine blade

摘要

A method for making a turbine blade (30) involving casting an internal skeleton (60) having a plurality of internal ribs (64) which form a plurality of open cooling channels (62); applying a filler material (74) to the open cooling channels (62); and applying an outer wall (76) about the internal skeleton (60) having the filler material (74) applied to the open cooling channels (62) where the internal skeleton (60) and the outer wall (76) are made from different superalloy materials.
