Document Type and Number:
Japanese Patent JP2017089630
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of providing a support for formation of very thin walls that bound cooling holes using an additive manufacturing process.SOLUTION: A method of forming a passage (122) in a turbine component (10) includes: using an additive manufacturing process to form a first support structure (162) on a first surface (156) of the turbine component (10); and forming a passage (122) through the first support structure (162) and the turbine component (10).SELECTED DRAWING: Figure 8
