Document Type and Number:
Japanese Patent JP6405357
Kind Code:
B2
Abstract:
A method of forming a cooling hole structure on a turbine component is disclosed. The turbine component has a component wall (120) with inner and outer surfaces. A bore (122) passes through the component wall and fluidly connects the inner surface and the outer surface. The method includes the steps of: forming a recess (132) with surfaces (131) communicating with the bore (122) and the outer surface; and using an additive manufacturing process to form an exit region in the recess (132). In an embodiment, a plug (134) is formed in the bore (122).
