    摘要： Methods for forming a sintered bond coat (64) on a silicon-based substrate (14) and articles (50) formed by the methods are disclosed. The methods include applying a bond coat slurry on the silicon-based substrate (14), drying the bond coat slurry on the silicon-based substrate to form a dried bond coat (44), and sintering the dried bond coat (44) in an oxidizing atmosphere to form a sintered bond coat (64) on the silicon-based substrate (14). The bond coat slurry includes a bond coat patching material in a bond coat fluid carrier. The articles (50) include a silicon-based substrate (14), a sintered bond coat (64) formed on the silicon-based substrate (14), and a sintered environmental barrier coating (EBC) (66) formed on the sintered bond coat (64). The sintered bond coat (64) includes a silicon-based phase and an oxide of the silicon-based phase.

    摘要： 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.

    摘要： A coated seal slot system (10, 200, 500, 600, 700) for turbomachinery includes a first turbine component (20, 220) comprising a first groove (30, 230) having at least one first coating (40, 240, 540, 640, 702) attached to at least a portion of the first groove of the first turbine component, a second turbine component (60, 260) comprising a second groove (70, 270) having at least one second coating (80, 280, 580, 680, 702) attached to at least a portion of the second groove of the second turbine component. The first and the second turbine components are disposable adjacent to each other with the first groove having the first coating and the second groove having the second coating together forming a coated seal slot (100, 400) extending across a gap (12, 212) between the first turbine component and the second turbine component. A seal (110, 310) is disposable in the coated seal slot and extendable across the gap between the first and the second turbine components and engageable with the first coating and the second coating to inhibit leakage of gas through the gap.
