Title:
LATTICE STRUCTURE IN COOLING PATHWAY BY ADDITIVE MANUFACTURE
Document Type and Number:
Japanese Patent JP2018204603
Kind Code:
A
Abstract:
To provide a hot gas path (HGP) component including a cooling pathway that includes a lattice structure therein.SOLUTION: A hot gas path component of an industrial machine includes a cooling pathway with a lattice structure therein. The component and lattice structure are made by additive manufacturing. The component includes an outer surface exposed to a working fluid having a high temperature; a thermal barrier coating over the outer surface; an internal cooling circuit; and a cooling pathway in communication with the internal cooling circuit and extending towards the outer surface. The lattice structure is in the cooling pathway at the outer surface. The lattice structure is configured to support the thermal barrier coating over the cooling pathway and, in response to fracture in the thermal barrier coating occurring over the cooling pathway, allow a cooling medium from the internal cooling circuit to pass through the lattice structure.SELECTED DRAWING: Figure 5
