Abstract: Composite components and methods for adding a composite material to a composite component are provided. For example, a method comprises positioning a composite material segment against the composite component to form a component layup; applying an insulating material around at least a portion of the component layup to form an insulated layup; and densifying the insulated layup, where the composite component was previously densified before positioning the composite material segment against the composite component. In some embodiments, the composite material is ceramic matrix composite (CMC) and the composite material segment is a plurality of CMC plies. The composite component may be a CMC gas turbine engine component that comprises an original CMC component and a new CMC material segment joined to the original CMC component through the transfer of silicon between the original CMC component and the new CMC material segment during melt infiltration.

Abstract: A method is provided in which a first tape is applied to an outer surface of a ceramic matrix composite (CMC). A second tape is applied to the first tape. The second tape is heated to at least a melting temperature of the second tape. During heating, the first tape is infiltrated with a molten material from the second tape, which forms a surface layer on the CMC.

Abstract: In joining composite ceramic bodies, at least one ceramic body is a compositionally graded with varying concentrations between two or more ceramic materials. The compositionally graded ceramic body terminates at an interfacial layer that is substantially composed of a single ceramic material. The compositionally graded ceramic body is joined to another ceramic body that may also be compositionally graded or made of a single ceramic material, and an interfacial layer of the other ceramic body is identical in composition with the interfacial layer of the compositionally graded ceramic body. In some embodiments, the ceramic bodies may be joined by diffusion bonding. In some embodiments, the ceramic bodies include a ceramic platen and ceramic stem of a wafer pedestal implemented in a plasma processing apparatus.

Abstract: A preparation method of heat-resistant adhesive of silicon-boron-carbon-zirconium modified aluminum-zirconium phosphate for zirconium oxide ceramics is provided. The high-temperature adhesive can generate various high-temperature resistant phases such as zirconia, aluminum phosphate, zirconium phosphate and aluminum borate in situ of the high-temperature adhesive at high temperatures. As the processing temperature increases, the content of zirconia in the high-temperature adhesive continuously increases, and the composition tends to form a stable composite phase mainly composed of aluminum phosphate and zirconia, which makes the composition of the high-temperature adhesive closer to that of zirconia ceramics.
