TURBINE BLADE COOLING CHANNEL FORMATION

摘要

PROBLEM TO BE SOLVED: To provide formation of cooling channels on a surface of a turbine blade and turbine blades including such cooling channels.SOLUTION: A method of forming cooling channels 20 along a surface 10 of a turbine blade 1 comprises the steps of: applying a first mask material to a first portion of the surface of the turbine blade; forming a first barrier layer atop the first mask material and atop a second portion of the surface of the turbine blade; removing the first mask material and the barrier layer atop the first mask material to expose the first portion of the surface of the turbine blade; and etching the first portion of the surface of the turbine blade to form the cooling channels along the surface of the turbine blade.
