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.
