Abstract
A system includes a layered structure. The layered structure includes first and second coalesced layers and an intermediate layer disposed between the first and second coalesced layers. The first and second coalesced layers have a higher degree of coalescence than the intermediate layer.
Claims20
A method of manufacturing a layered structure for a turbomachine component, comprising:
- selectively heating a first powder to form a first coalesced layer having a first degree of material density;
- selectively heating a second powder to form a second coalesced layer having a second degree of material density;
- and
- disposing an intermediate layer between the first and second coalesced layers, wherein the intermediate layer comprises an evacuated region configured to serve as a thermal barrier, an acoustic barrier, or a combination thereof between the first coalesced layer and the second coalesced layer.

A method of manufacturing a structure having layers coalesced from one or more powder materials, comprising:
- heating a first powder to coalesce a first layer of the layered structure, wherein the first layer comprises a first material density;
- heating a second powder to coalesce a second layer of the layered structure, wherein the second layer comprises a second material density;
- and
- spacing the first layer from the second layer such that an intermediate layer of the layered structure is disposed between the first layer and the second layer, wherein the first material density and the second material density are greater than an intermediate material density of the intermediate layer.

A turbomachine component having a layered structure, the layered structure comprising:
- a first coalesced powder layer of the turbomachine component, wherein the first coalesced layer comprises a first material density;
- a second coalesced powder layer of the turbomachine component, wherein the second coalesced layer comprises a second material density;
- and
- an intermediate layer disposed between the first and second coalesced layers, wherein the intermediate layer comprises a material density less than the first material density and the second material density.
