Abstract: In some examples, the disclosure describes an article and a method of making the same that includes a substrate including a ceramic or a ceramic matrix composite including silicon carbide, where the substrate defines an outer substrate surface and a plurality of grooves formed in the outer substrate surface, where each respective groove of the plurality of grooves exhibits an anchor tooth that spans an edge of the respective groove, and where the plurality of grooves define an average groove width less than about 20 micrometers, and a coating formed on the outer surface of the substrate, where the coating at least partially fills the plurality of grooves of the substrate.
