Abstract
A multi-layer coating arrangement includes an environmental barrier coating (EBC) over a substrate; and at least one dense vertically cracked (DVC) coating layer over the EBC. The at least one DVC layer is resistant to erosion, water vapor corrosion and to calcium-magnesium-aluminum-silicate (CMAS).
Claims21
A multi-layer coating arrangement comprising:
- an environmental barrier coating (EBC) over a substrate;
- and
- at least one dense vertically cracked (DVC) coating layer over the EBC, the at least one DVC layer being resistant to at least one of erosion, water vapor corrosion, and calcium-magnesium-aluminum-silicate (CMAS).
-26. (canceled)
A method of forming a coating that is resistant to erosion, water vapor corrosion and to CMAS on a substrate coated with at least one EBC coating layer, the method comprising:
- plasma spraying a DVC coating material over the at least one EBC coating layer.
