Beschreibung
Zusammenfassung:	Embodiments of the invention relate generally to turbine blades and, more particularly, to the formation of cooling channels on a surface of a turbine blade and turbine blades including such cooling channels. In one embodiment, the invention provides a method of forming a cooling channel along a surface (10) of a turbine blade, the method comprising: applying a first mask material (30) to a first portion (12) of a surface (10) of a turbine blade; forming a first barrier (40) layer atop the first mask material (30) and atop a second portion (14) of the surface (10) of the turbine blade; removing the first mask material (30) and the barrier layer (40) atop the first mask material (30) to expose the first portion (12) of the surface (10) of the turbine blade; and etching the first portion (12) of the surface (10) of the turbine blade to form a cooling channel (20) along the surface (10) of the turbine blade.
