Abstract: Systems and methods for thermally processing composite components are provided. In one exemplary aspect, a system includes a thermal system, a mover device, and a control system. The system also includes a plurality of vessels in which one or more components may be placed. The vessels are similarly shaped and configured. A vessel containing the one or more components therein may be mounted into a chamber defined by the thermal system during thermal processing. The thermal system and vessels include features that allow components to be thermally processed, e.g., compacted, burnt-out, and densified via a melt-infiltration process, a polymer impregnation and pyrolyzing process, or a chemical vapor infiltration process. utilizing the same thermal system and common vessel design. The control system may control the thermal system and mover device to automate thermal processing of the composite components.

Abstract: Systems and methods for recovery of rare-earth constituents from environmental barrier coatings are provided. One method includes extracting rare-earth (RE) oxide constituents from a feedstock containing RE silicates and non-RE contaminants. The method includes leaching the REs from the feedstock into an acid to form an acid solution, performing an oxalate precipitation on the acid solution to form an RE oxalate hydrate, and separating the RE oxalate hydrate from the acid solution. The method also includes heat treating the RE oxalate hydrate to form an RE oxide containing the RE elements extracted from the feedstock.

Abstract: A system for coating ceramic fibers for use in manufacturing a ceramic matric composite (CMC) article includes a frame having a plurality of frame members arranged so as to create a void therebetween. At least one of frame members includes a hollow body and at least one perforated hole defined in the hollow body. Thus, the ceramic fibers are securable at respective ends of the frame and extend across the void. The frame also includes an inlet in fluid communication with the perforated hole(s) so as to allow a coating material to flow into and through the hollow body and out of the perforated hole(s) at a location of at least a portion of one of the ceramic fibers. As such, the coating material is configured to cause the portion of one of the ceramic fibers to separate from the frame such that the portion is uniformly coated with the coating material.

Abstract: A method for controlling the porosity parameter of porous thermal barrier coatings is presented. The method includes disposing a feedstock material on a substrate to form a porous thermal barrier coating. The feedstock material includes a gas-forming additive and a thermal barrier coating material. The disposing step further includes controlling the porosity parameter of the porous thermal barrier coating by controlling a feedstock material feed rate, an amount of the gas-forming additive in the feedstock material, a temperature of the disposed feedstock material on the substrate, or combinations thereof.

Abstract: Methods for coating a fiber are provided. The method can include unwinding a silicon carbide-containing fibrous material from a bobbin rotatably mounted around an axle and forming a boron nitride coating onto the silicon carbide-containing fibrous material. The bobbin is moved along the axial direction such that the silicon carbide-containing fibrous material defines an unwind angle with the axial direction, with the unwind angle being maintained between about 80° to about 100°.
