Subsurface inclusion of fugitive objects and methodology for strengthening a surface bond in a hybrid ceramic matrix composite structure

A hybrid ceramic matrix composite structure, comprising:

• a ceramic matrix composite substrate including a plurality of layers of ceramic fibers;
• a plurality of spaced apart fugitive objects disposed on at least one of the plurality of layers prior to laying a subsequent layer of ceramic fibers onto said at least one of the plurality layers, wherein, due to the fugitive objects, an outer surface of said subsequent layer influences a shape of an outer surface of the substrate by defining a plurality of protuberances on the outer surface of the substrate, wherein respective cavities are formed beneath respective protuberances upon dissipation of the fugitive objects, wherein respective openings define respective entrances to the cavities;
• a ceramic coating deposited in a fluid state on the outer surface of the ceramic substrate, wherein the respective entrances pass at least some of the fluid into the cavities to fill the cavities, wherein the ceramic coating is cured to a solidified state, wherein the cavities containing the solidified coating constitute an anchoring arrangement between the ceramic substrate and the ceramic coating.
