Abstract: The present invention is directed to repair compositions for thermal barrier coatings and methods of use thereof. The repair compositions include a ceramic composition, a colloidal solution, an aqueous binder, an aqueous dispersant, and an aqueous ammonia solution. The ceramic composition includes a first population of yttria-stabilized zirconia particles having a mean diameter from about 250 nm to about 1000 nm, a second population of yttria-stabilized zirconia particles having a mean diameter from about 2 µm to about 10 µm, and a third population of yttria-stabilized zirconia particles having a mean diameter from about 20 µm to about 250 µm. One method includes depositing the repair layer onto the damaged region, the repair layer including the repair composition, and heat treating the repair layer.

Abstract: The turbomachine includes a compressor, an inner annular casing, and an outer annular casing. The inner annular casing and the outer annular casing define at least one cavity therebetween. The clearance control system includes a manifold system including at least one conduit disposed within the cavities and configured to channel a flow of cooling fluid between the cavities. The clearance control system also includes an impingement system including a header and at least one plenum configured to channel the flow of cooling fluid to the inner annular casing. The conduits configured to channel the flow of cooling fluid to the impingement system. The clearance control system further includes a channel system including at least one channels configured to channel the flow of cooling fluid to the turbomachine. The channels are configured to control the flow of cooling fluid to the manifold system.

Abstract: A method for forming a patch repair on a silicon-based component (30) is disclosed. The method includes applying a patch on a damaged area (32, 34, 36) of a silicon-based component (30), drying the patch to form a dried patch, and sintering in situ the dried patch to form a patch repaired portion (42, 44, 46) of the silicon-based component. The patch includes a patching material and the patching material includes a plurality of nanoparticles having a median particle size less than 100 nanometers. The plurality of nanoparticles includes at least one of silicon, silicon alloy, silica, or a metal silicate.
