Abstract: Components and methods for producing such components are provided. The component comprises a substrate having a ceramic material, and a coating system on a surface of the substrate. The coating system includes one or more layers defining a composition gradient. A first portion of the coating system closest to the surface of the substrate has a composition comprising at least 95 wt. % of a rare earth disilicate, a second portion of the coating system furthest from the surface of the substrate has a composition comprising at least 50 wt. % of a rare earth monosilicate, and a third portion between the first portion and the second portion has a composition comprising both the rare earth disilicate and the rare earth monosilicate.
