Components are disclosed which include a CMC substrate having a first surface and a second surface. The first surface is in fluid communication with a compressed, dry fluid, and the second surface is in fluid communication with a wet fluid stream and includes a hermetic coating. The components further include at least one opening extending from the first surface through a portion of the CMC substrate, wherein, upon removal of a fragment of one or both of the hermetic coating and the CMC substrate, the at least one opening selectively permits a flow of the compressed, dry fluid to the second surface. In one embodiment, the component is a gas turbine component, the wet fluid stream is a hot combustion stream, the hermetic coating is an environmental barrier coating, and the flow reduces or eliminates volatilization of the CMC substrate. Methods for forming the components are also disclosed.

1. A turbine component, comprising: a ceramic matrix composite (CMC) substrate having a first surface and a second surface, wherein: the first surface is in fluid communication with a compressed, dry fluid;the second surface is in fluid communication with a wet fluid stream, the compressed, dry fluid having a moisture content lower than the wet fluid stream; andthe second surface includes a hermetic coating; andat least one opening extending from the first surface through a portion of the CMC substrate, wherein the hermetic coating is disposed over each such opening, and, upon removal of a fragment of one or both of the hermetic coating and the CMC substrate, the at least one opening selectively permits a flow of the compressed, dry fluid to the second surface,wherein the flow is sufficient to reduce or eliminate volatilization of the CMC substrate in the wet fluid stream, andwherein the component is a turbine component selected from the group consisting of a shroud, a shroud ring, and a combustion liner. 2. The turbine component of claim 1, wherein the hermetic coating is an environmental barrier coating. 3. The turbine component of claim 2, wherein the environmental barrier coating comprises silicon carbide. 4. The turbine component of claim 1, wherein the at least one opening extends from the first surface to the hermetic coating. 5. The turbine component of claim 1, wherein the at least one opening extends partially through the CMC substrate. 6. The turbine component of claim 1, wherein the CMC substrate comprises a material selected from the group consisting of carbon-fiber-reinforced carbon (C/C), carbon-fiber-reinforced silicon carbide (C/SiC), silicon-carbide-fiber-reinforced silicon carbide (SiC/SiC), alumina-fiber-reinforced alumina (Al2O3/Al2O3), and combinations thereof. 7. The turbine component of claim 1, wherein the at least one opening includes a diffuser at one end. 8. The turbine component of claim 1, wherein the at least one opening is positioned at an oblique angle to the second surface. 9. The turbine component of claim 1, wherein the wet fluid stream is a hot combustion stream. 10. A gas turbine component, comprising: a ceramic matrix composite (CMC) substrate having a first surface and a second surface, wherein: the first surface is in fluid communication with a compressed, dry fluid;the second surface is in fluid communication with a hot combustion stream, the compressed, dry fluid having a moisture content lower than the hot combustion stream; andthe second surface includes an environmental barrier coating; andat least one opening extending from the first surface through a portion of the CMC substrate, wherein the environmental barrier coating is disposed over each such opening, and, upon removal of a fragment of one or both of the environmental barrier coating and the CMC substrate, the at least one opening selectively permits a flow of the compressed, dry fluid to the second surface and reduces or eliminates volatilization of the CMC substrate in the hot combustion stream,wherein the gas turbine component is selected from the group consisting of a shroud, a shroud ring, and a combustion liner. 11. A method of forming a component, comprising: forming at least one opening in a ceramic matrix composite (CMC) substrate of a turbine component, wherein the turbine component is selected from the group consisting of a shroud, a shroud ring, and a combustion liner, and wherein the at least one opening extends from a first surface through a portion of the CMC substrate; andforming a hermetic coating on a second surface of the CMC substrate, the hermetic coating being disposed over each such opening and the second surface being in fluid communication with a wet fluid stream,wherein upon removal of a fragment of one or both of the hermetic coating and the CMC substrate, the at least one opening selectively permits a flow of a compressed, dry fluid to the second surface, the compressed, dry fluid having a moisture content lower than the wet fluid stream, and the flow is sufficient to reduce or eliminate volatilization of the CMC substrate in the wet fluid stream. 12. The method of claim 11, wherein the hermetic coating is formed prior to the forming of the at least one opening in the CMC substrate. 13. The method of claim 11, wherein the hermetic coating is formed after the forming of the at least one opening in the CMC substrate. 14. The method of claim 11, wherein the hermetic coating is an environmental barrier coating. 15. The method of claim 11, wherein forming the at least one opening includes mechanical drilling, laser drilling, or a combination thereof. 16. The method of claim 11, wherein the at least one opening extends from the first surface to the hermetic coating. 17. The method of claim 11, wherein the at least one opening extends partially through the CMC substrate.
