ABSTRACT:
A method of forming an airfoil-shaped body is described which includes providing a core with cooling channels recessed into the surface thereof, affixing a calendered multilayer flexible mesh screen substrate to the surface of the core, applying braze alloy and brazing the assembly thereby filling completely the mesh screen pores and bonding further the mesh member substrate to the core, and applying an erosion-corrosion resistant layer over the brazed mesh member substrate completing the airfoil-shaped body.
