CLAIMS

What we claim is:

1 . A component (10) comprising:

a substrate (12) comprising a ceramic matrix composite material (14);

a thermal barrier coating layer (18) disposed over the substrate (12); and an intermediate thermal protection and adhesion layer (16) between the thermal barrier coating layer (18) and the substrate (12) effective to adhere the thermal barrier coating layer (18) to the substrate (12) and provide a degree of thermal protection to the substrate (12) upon spallation of the thermal barrier coating layer (18).

2. The component (10) of claim 1 , wherein the intermediate layer (16) comprises a rare earth oxide.

3. The component (10) of claim 1 , wherein the intermediate layer (16) comprises an yttrium-containing material.

4. The component (10) of claim 1 , wherein the yttrium-containing material comprises a member selected from the group consisting of yttrium aluminum garnet, yttrium oxide, and combinations thereof.

5. The component of claim 1 , wherein the intermediate layer (16) comprises a thickness of from 50 micron to 300 micron.

6. The component (10) of claim 1 , wherein the thermal barrier coating layer (18) has a thickness of from 50 to 2000 micron.

7. The component (10) of claim 1 , wherein the thermal barrier coating layer (18) comprises a zirconia-based material.

8. The component (10) of claims 1 to 7, wherein the ceramic matrix composite material (14) comprises an oxide-oxide material.
