Abstract: A coated component may have a consumable coating that protects the component from dust. A coated component may include a silicon containing substrate defining a substrate surface, a barrier coating on the substrate surface, with the barrier coating defining a barrier surface, and a consumable coating on the barrier surface. The consumable coating may include a ceramic oxide that includes a silicate. A component, such as a component of a turbomachine, may be protected from dust by applying a consumable coating on the component.

Abstract: An coated component is provided. The coated component includes a component substrate and bond coat layer comprising silicon deposited on the component substrate. A composite layer is deposited on the bond coat layer. The composite layer includes a rare earth disilicate and a second phase material. The composite layer has a thickness (T) from about 0.05 mm to about 2.25 mm, and a coefficient of thermal expansion that is different by a value of about 0 to about 2.25 from a coefficient of thermal expansion of the component substrate upon which the bond coat layer is deposited. Coated gas turbine engine components are also provided.
