Claim:
1. A turbine component, comprising: a ceramic matrix composite (CMC) substrate having a first surface and a second surface, wherein: at 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, and wherein the component is a turbine component selected from the group consisting of a shroud, a shroud ring, and a combustion liner.
