1. A method, comprising:
forming a first layer of a first coating material on a substrate of a component, wherein the first coating material includes a rare earth silicate, the substrate of the component includes silicon nitride, and the first layer has a first thickness; and
forming a second layer of a second coating material on the first layer, wherein the second coating material includes a rare earth silicate and the second layer has a second thickness that is greater than the first thickness of the first layer, wherein the second layer is formed in a manner to intentionally cause formation of mud cracks in the second layer that extend from an exterior surface thereof toward the substrate, wherein the second thickness is sufficient to cause the mud cracks to form having widths in a range of about 50 to 200 micrometers.
