摘要
A system for forming a surface coating on an outer surface of a foam for use with cooling system of turbine engines. The system may include removing filler from the outer surface of the foam to expose a porous structure of the foam, whereby portions of the porous structure extend outwardly from a newly formed outer surface of the filler. A surface layer may be applied to the outer surface of the filler and exposed portions of the porous structure, whereby the surface layer is attached to the porous structure at least in part due to mechanical interaction with the portions of the porous structure extending outwardly from the newly formed outer surface of the filler. The filler material may then be removed from the porous structure.
