First claim

Opening claim text (preview).

What is claimed is: 1. A gas turbine engine component comprising: a structure having a surface, the surface including multiple cooling channels having a width of 20-30 μm and a depth of 25-50 μm, wherein the structure includes a substrate, a thermal barrier coating is adhered to the substrate with a bond coat having a uniform thickness, the thermal barrier coating providing the surface with the channels provided only in the thermal barrier coating such that the bond coat is arranged on a side of the thermal barrier coating opposite the channels, wherein the cooling channels are arranged in an intersecting pattern. 2. The gas turbine engine component according to claim 1 , wherein the surface is a line-of-sight surface. 3. The gas turbine engine component according to claim 1 , wherein the structure is an airfoil having an internal cooling passage. 4. The gas turbine engine component according to claim 1 , wherein the substrate is a nickel alloy, and the thermal barrier coating is a ceramic. 5. The gas turbine engine component according to claim 1 , wherein the cooling channels include a generally U-shaped cross-section. 6. The gas turbine engine component according to claim 1 , wherein the cooling channels include a generally V-shaped cross-section. 7. The gas turbine engine component according to claim 1 , wherein the cooling channels form pyramid shaped structures. 8. The gas turbine engine component according to claim 1 , wherein the cooling channels are arranged at acute angles relative to one another. 9. A gas turbine engine component comprising: a structure having a surface, the surface including multiple cooling channels having a width of 20-30 μm and a depth of 25-50 μm, wherein the structure includes a substrate, a thermal barrier coating is adhered to the substrate with a bond coat having a uniform thickness, the thermal barrier coating providing the surface with the channels provided only in the thermal barrier coating such that the bond coat is arranged on a side of the thermal barrier coating opposite the channels, wherein the cooling channels are arranged in a circular pattern. 10. The gas turbine engine component according to claim 9 , wherein the surface is a line-of-sight surface. 11. The gas turbine engine component according to claim 9 , wherein the structure is an airfoil having an internal cooling passage. 12. The gas turbine engine component according to claim 9 , wherein the substrate is a nickel alloy, and the thermal barrier coating is a ceramic. 13. The gas turbine engine component according to claim 9 , wherein the cooling channels include a generally U-shaped cross-section. 14. The gas turbine engine component according to claim 9 , wherein the cooling channels include a generally V-shaped cross-section. 15. A gas turbine engine component comprising: a structure having a surface, the surface including multiple cooling channels having a width of 20-30 μm and a depth of 25-50 μm, wherein the structure includes a substrate, a thermal barrier coating is adhered to the substrate with a bond coat having a uniform thickness, the thermal barrier coating providing the surface with the channels provided only in the thermal barrier coating such that the bond coat is arranged on a side of the thermal barrier coating opposite the channels, wherein the cooling channels provide a circular recess without circumscribing the structure. 16. The gas turbine engine component according to claim 15 , wherein the surface is a line-of-sight surface. 17. The gas turbine engine component according to claim 15 , wherein the structure is an airfoil having an internal cooling passage. 18. The gas turbine engine component according to claim 15 , wherein the substrate is a nickel alloy, and the thermal barrier coating is a ceramic. 19. The gas turbine engine component according to claim 15 , wherein the cooling channels include a generally U-shaped cross-section. 20. The gas turbine engine component according to claim 15 , wherein the cooling channels include a generally V-shaped cross-section.
