Abstract
A coated ceramic matrix composite component and a gas turbine assembly are provided. The coated ceramic matrix composite component comprises a substrate comprising an endface surface and a hot gas path surface. The hot gas path surface is arranged and disposed to contact a hot gas path when the component is installed in the gas turbine assembly. The endface surface is disposed at an endface angle to the hot gas path surface and opposing at least one adjacent component when the component is installed in the gas turbine assembly. The coated ceramic matrix composite component further comprises an environmental barrier coating on at least a portion of the endface surface.

A coated ceramic matrix composite component for a gas turbine, comprising:
- a substrate comprising an endface surface and a hot gas path surface, the hot gas path surface being arranged and disposed to contact a hot gas path when the component is installed in the gas turbine, and the endface surface being disposed at an endface angle to the hot gas path surface and opposing at least one adjacent component when the component is installed in the gas turbine;
- and
- an environmental barrier coating on at least a portion of the endface surface.
A gas turbine assembly comprising:
- a coated ceramic matrix composite component comprising:
- a substrate comprising an endface surface and a hot gas path surface, the hot gas path surface being arranged and disposed to contact a hot gas path, and the endface surface being disposed at an endface angle to the hot gas path surface;
- and
- an environmental barrier coating on at least a portion of the endface surface;
- and
- at least one adjacent component,
- wherein the endface surface is disposed opposing the at least one adjacent component.
A method for forming a coated ceramic matrix composite component for a gas turbine, comprising:
- providing a component comprising a substrate comprising an endface surface and a hot gas path surface;
- and
- forming an environmental barrier coating on at least a portion of the endface surface;
- wherein the hot gas path surface is arranged and disposed to contact a hot gas path when the component is installed in the gas turbine, and the endface surface is disposed at an endface angle to the hot gas path surface and opposing at least one adjacent component when the component is installed in the gas turbine.
