摘要：Methods for repairing a turbine airfoil constructed from a CMC material areprovided via filling a cavity located in the turbine airfoil with a ceramic paste (e.g.,including a ceramic powder and a binder), heating the ceramic paste in the cavity toremove the binder, thereby forming a porous ceramic material, and adding a moltenceramic material to the porous ceramic material. The cavity can be defined in an airfoil ofthe turbine airfoil (e.g., on a tip or cap of the airfoil). Intermediates formed during therepair of a turbine airfoil are also provided. The intermediate can generally include anairfoil comprising a CMC material, a cavity defined in the airfoil, and a porous ceramicmaterial filling the cavity.
