摘要： A planetary carrier subassembly for a transmission is provided that is sintered using braze preforms. The carrier subassembly may include a powder metal carrier member having a plurality of carrier legs extending a distance therefrom, and a powder metal cover member having a plurality of cover legs extending a distance therefrom. The carrier member and cover member are positioned such that respective ends of the carrier legs and ends of the cover legs are aligned with one another. The subassembly is provided with at least one braze preform including a braze material and a sacrificial binder, such as a wax. The braze preform is placed between a respective pair of the aligned carrier legs and the cover legs. The braze preform is provided with a geometry configured to direct a flow of braze material during a subsequent sintering process.

摘要： A mold assembly system includes a mold assembly that defines an infiltration chamber used for forming an infiltrated metal-matrix composite (MMC) tool. Reinforcement materials are deposited within the infiltration chamber, and a binder material is used to infiltrate the reinforcement materials. At least one preformed mesh is positioned within the infiltration chamber and embedded within the reinforcement materials. The at least one preformed mesh includes a porous body and provides skeletal reinforcement to the infiltrated MMC tool following infiltration.

摘要： Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion.

摘要： A mold assembly system includes a mold assembly that defines an infiltration chamber used for forming an infiltrated metal-matrix composite (MMC) tool, and at least one boundary form positioned within the infiltration chamber and segregating the infiltration chamber into at least a first zone and a second zone. Reinforcement materials are deposited within the infiltration chamber and include a first composition loaded into the first zone and a second composition loaded into the second zone. At least one binder material infiltrates the first and second compositions, wherein infiltration of the first and second compositions results in differing mechanical, chemical, physical, thermal, atomic, magnetic, or electrical properties between the first and second zones in the infiltrated MMC tool.

摘要： A blade for a gas turbine includes a removed portion space, and further includes an airfoil portion defining the removed portion space, the airfoil portion formed from a base material, and a replacement component formed to fill the removed portion space. The replacement component is formed from a material that includes 50%-80% base material, 0%-30% braze material, and 0%-8% aluminum. A braze joint is formed between the airfoil portion and the replacement component to attach the replacement component to the airfoil portion and fill the removed portion space.

摘要： The present disclosure relates to a hierarchical wear part including a reinforced portion comprising zirconia or an alumina-zirconia alloy. The reinforced portion also includes centimetric inserts with a predefined geometry. The inserts include micrometric particles of metal carbides, nitrides, borides, or intermetallic compounds bonded by a first metal matrix. The inserts are inserted into a reinforcement structure infiltrated by a second metal matrix, the reinforcement structure having a periodic alternation of millimetric areas of high and low concentration of micrometric particles of zirconia or alumina-zirconia alloy. The second metal matrix is different from the first metal matrix.
