  • Patent number: 6872464
    Abstract: A soldering agent for use in diffusion soldering processes contains, in a soldering paste, a mixture of at least partially metallic grains of a high-melting metal and a solder metal. In a diffusion soldering process, the solder metal reacts completely with the high-melting metal and metals belonging to parts that are to be joined to one another by the soldering process, to form an intermetallic phase.

  • Publication number: 20040110021
    Abstract: A wear alloy coating (14) applied to a substrate material (12) by a cold spray process. Particles of the wear alloy coating material (16) are directed toward a target surface (18) of the substrate at a velocity sufficiently high for the particles to deform and to adhere to the target surface. The size and composition of the particles may be varied during the cold spray process to produce a coating with a varying property across the depth of the coating. Particles of the wear alloy material may be applied by cold spraying along with particles of a second material such as a lubricant or a ceramic material. For Group 5 hard facing materials, the size and distribution of the embedded carbide nodules may be controlled by controlling the selection of the carbide particles being sprayed. The cold spray process permits a wear alloy coating to be applied proximate a brazed joint or over a directionally stabilized or single crystal material without degrading the underlying material.

  • Patent number: 6670049
    Abstract: An environmental coating is applied to the surface of a titanium-base alloy substrate to protect the surface from oxidation, corrosion, erosion, and other damage. The coating is a mixture of a metal and a ceramic, each selected to contribute to the protective function. The proportions of the metal and the ceramic in the coating are selected such that the coefficient of thermal expansion of the coating is about the same as the coefficient of thermal expansion of the substrate.

  • Publication number: 20030207142
    Abstract: A method for making aerospace face seal rotors reinforced by rhenium metal, alloy, or composite in combination with silicon carbide or other ceramic. The resulting rotor also is disclosed. Ceramic grains, preferably silicon carbide (SiC), are mixed with powdered metallic (PM) binder that may be based on a refractory metal, preferably rhenium. The mixture is applied to a rotor substrate. The combined ceramic-metal powder mixture is heated to sintering temperature under pressure to enable fusion of the ceramic in the resulting metal-based substrate. A load may then be applied under an elevated temperature. The resulting coated rotor can exhibit high hot hardness, increased durability and/or high hot wear resistance, as well as high thermal conductivity.
