Metal To Nonmetal With Separate Metallic Filler Patents (Class 228/122.1)
  • Patent number: 9449742
    Abstract: An electrode component includes a ceramic substrate, two electrode layers formed on two opposite surfaces of the ceramic substrate, two pins respectively connected to the two electrode layers, and an insulating layer enclosing the ceramic substrate, the electrode layers and a portion of each pin. Each electrode layer is formed of two or more base metal materials or alloys thereof, and the concentrations of the base metal materials progressively vary across the electrode layer. Accordingly, the production cost is lowered, environmental pollution caused by evaporation and thermal dissolution of organic solvent can be prevented, risk of separable electrode interface at high-voltage discharge is mitigated, and the fabrication process of the electrode layer is shortened while maintaining bonding strength between the electrode layers and the ceramic substrate and solderability between the electrode layers and the pins.

A substrate (22) is formed from a metal powder (70), and may be partially sintered (60). A layer (24) of ceramic powder is arranged on the substrate including the pre-sintered hollow ceramic spheres plus a proportion of nano-sized ceramic particles effective to reduce the layer sintering temperature and to increase the sintering shrinkage of the layer to approximate that of the metal substrate during subsequent co-sintering. The substrate and layer are then co-sintered (61), such as with spark plasma sintering (32, 34, 36), at a temperature and for a duration to fully densify the ceramic powder matrix around the hollow spheres, thereby producing a metal/ceramic material system with low interface stress and with stable porosity during operational temperatures in a gas turbine engine.

A flux is used in order to activate the solder, and the electric and mechanical connection is carried out by means of a soldering process under the effect of heat and by melting the solder/flux mixture with the inclusion of a subsequent cooling phase. According to the invention, the joining partners and the solder are heated to a temperature below the activation temperature of the solder and the flux in a first temperature treatment phase. Another heating process is then carried out to a temperature above the activation temperature of the flux up to the upper melting range of the solder in a second temperature treatment phase, wherein the solder melts and begins to connect to the respective joining partners.

    Abstract: Systems, methods, and devices that have a hermetic seal formed using reflow soldering are provided. The hermetic seal may protect electrical components within a packaging for use in downhole tools and/or other applications where the electrical components may be exposed to extreme environments. In one example, an electronic device includes a ceramic substrate having a plated ring. The electronic device also includes a metal lid. A high-temperature solder is disposed between the plated ring of the ceramic substrate and the metal lid. The electronic device includes a hermetically sealed cavity formed between the ceramic substrate and the metal lid. The hermetically sealed cavity is formed via a first bond between the plated ring of the ceramic substrate and the high-temperature solder, and via a second bond between the metal lid and the high-temperature solder. Moreover, the first and second bonds are formed using reflow soldering.

  • Patent number: 8701970
    Abstract: A method of forming and assembling at least two parts together that may be metal, ceramic, or a combination of metal and ceramic parts. Such parts may have different CTE. Individual parts that are formed and sintered from particles leave a network of interconnecting porosity in each sintered part. The separate parts are assembled together and then a fill material is infiltrated into the assembled parts using a method such as capillary action, gravity, and/or pressure. The assembly is then cured to yield a bonded and fully or near-fully dense part that has the desired physical and mechanical properties for the part's intended purpose. Structural strength may be added to the parts by the inclusion of fibrous materials.
