  • Patent number: 8609206
    Abstract: Surface metallization technology for ceramic substrates is disclosed herein. It makes use of a known phenomenon that many metal—metal oxide alloys in liquid state readily wet an oxide ceramic surface and strongly bond to it upon solidification. To achieve high adhesion strength of a metallization to ceramic, a discrete metallization layer consisting of metal droplets bonded to ceramic surface using metal—metal oxide bonding process is produced first. Next, a continuous metal layer is deposited on top of the discrete layer and bonded to it using a sintering process. As a result a strongly adhering, glass-free metallization layer directly bonded to ceramic surface is produced. In particular, the process can be successfully used to metalize aluminum nitride ceramic with high thermal and electrical conductivity copper metal.

    Abstract: A method and apparatus are disclosed for improving densification of porous substrate using a film boiling process. In particular, the disclosed method and apparatus permit more complete densification of a substrate (i.e., densification closer to the surface of the substrate) by selectively providing a sort of barrier that reduces cooling of the surface of the substrate being densified caused by contact with the relatively cool boiling liquid precursor of the densifying material, such as carbon. In particular, contact between the substrate and the liquid precursor is reduced using one or both of physical barriers (such as a mesh material) or structures that promote the formation of an insulating gaseous layer between the substrate and the liquid precursor (such as a plate closely spaced apart from the surface of the porous substrate). The barrier is moved into operational position before the applied power level increases sharply (as is known) near the end of the film boiling densification process.

  • Publication number: 20110117294
    Abstract: An apparatus and method for heating target surfaces to a temperature that inhibits, prevents or removes biofouling through induction heating includes an electromagnetic driver and control circuitry for generating electromagnetic energy within a select frequency range to match a target surface. An antenna emits the electromagnetic energy within a focused region to react with atoms/molecules in the target surface, thereby causing the target surface to be heated to a temperature within a controlled range. Increasing temperature sufficiently disrupts, kills or denatures biofouling organisms, biofilms and organic matter on the target surface and/or denatures biofilms on the surface. Coating materials may be applied to target surfaces to optimize the RF reactive molecular structure. A diagnostics, positioning and temperature sensor circuit communicates with the electromagnetic driver. A feedback circuit is used to maintain power level.

  • Publication number: 20100272923
    Abstract: A method and apparatus are disclosed for improving densification of porous substrate using a film boiling process. In particular, the disclosed method and apparatus permit more complete densification of a substrate (i.e., densification closer to the surface of the substrate) by selectively providing a sort of barrier that reduces cooling of the surface of the substrate being densified caused by contact with the relatively cool boiling liquid precursor of the densifying material, such as carbon. In particular, contact between the substrate and the liquid precursor is reduced using one or both of physical barriers (such as a mesh material) or structures that promote the formation of an insulating gaseous layer between the substrate and the liquid precursor (such as a plate closely spaced apart from the surface of the porous substrate). The barrier is moved into operational position before the applied power level increases sharply (as is known) near the end of the film boiling densification process.

  • Patent number: 7704553
    Abstract: A process for depositing nanometer-sized metal particles onto a substrate in the absence of aqueous solvents, organic solvents, and reducing agents, and without any required pre-treatment of the substrate, includes preparing an admixture of a metal compound and a substrate by dry mixing a chosen amount of the metal compound with a chosen amount of the substrate; and supplying energy to the admixture in an amount sufficient to deposit zero valance metal particles onto the substrate. This process gives rise to a number of deposited metallic particle sizes which may be controlled. The compositions prepared by this process are used to produce polymer composites by combining them with readily available commodity and engineering plastics. The polymer composites are used as coatings, or they are used to fabricate articles, such as free-standing films, fibers, fabrics, foams, molded and laminated articles, tubes, adhesives, and fiber reinforced articles.
