초록 ▼

The invention relates to a temperature resistant layered structure comprising a substrate and a porous layer arranged on the substrate having a pore defined by a wall, and a ceramic coating on an interior surface of the wall. The invention also relates to a layered turbine component arrangement comprising a substrate having a cooling passage adapted to allow a cooling gas medium to pass through the substrate and a porous layer arranged on the substrate, the porous layer having cooling passages formed by gas-permeable inter-connections between pores in the porous layer.

The invention claimed is: 1. A temperature resistant layered structure, comprising: a substrate formed of metallic or ceramic material; and a porous layer arranged on the substrate with an outer surface spaced away from the substrate, and having a plurality of pores formed therein with each pore defined by a wall, and a ceramic coating on an interior surface of the wall, the porous layer characterized by sizes of the pores decreasing as the layer extends toward the outer surface. 2. The layered structure of claim 1, wherein the layered structure is exposed to a temperature between 1000�� C. and 1600�� C. 3. The layered structure as claimed in claim 1, wherein the porous layer is in a foam or a sponge form. 4. The layered structure as claimed in claim 1, further comprising an intermediate layer interposed between the substrate and the porous layer. 5. The layered structure as claimed in claim 1, wherein the substrate and the porous layer comprise different materials. 6. The layered structure as claimed in claim 1, wherein the porous layer has a plurality of pores, each pore having the ceramic coating on the interior surface of the wall. 7. The layered structure as claimed in claim 1, wherein a ceramic coating is arranged on a surface region of the porous layer that is in contact with a hot working medium. 8. The layered structure as claimed in claim 1, wherein the porous layer is soldered, welded or adhesively bonded to the substrate, and the ceramic coating is applied to the pore by dip-coating, layer build-up or plasma spraying. 9. A temperature resistant layered structure, comprising: a substrate formed of metallic or ceramic material; and a porous layer arranged on the substrate with an outer surface spaced away from the substrate, and having a plurality of pores formed therein with each pore defined by a wall, and a ceramic coating on an interior surface of the wall, wherein the ceramic coating is ZrO2, or Y2O4--ZrO2, the porous layer characterized by sizes of the pores decreasing as the layer extends toward the outer surface.
