Title:
METHOD OF MANUFACTURING COOLING TURBINE BUCKET OR COMPRESSOR BUCKET
Document Type and Number:
Japanese Patent JPS5217106
Kind Code:
A
Abstract:
Before skins are brazed on airfoil cores having cooling channels recessed into the surfaces thereof, the surfaces of the cooling channel walls are covered with a layer of oxide material. The oxide formation selected is one that is not reducible in dry hydrogen. Thereafter, when the normally employed hydrogen or vacuum brazing operation is conducted to apply the airfoil skin, the oxide-covered sides of the cooling channels will not be wet by the molten braze alloy. Plugging of the covered cooling channels during manufacture is thereby greatly reduced.
