  • Publication number: 20040146642
    Abstract: A process for making functional or decorative flakes or platelets economically and at high production rates comprises applying a multi-layer sandwich of vapor deposited metal and release coats in alternating layers to a rotating chilled drum or suitable carrier medium contained in a vapor deposition chamber. The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent soluble thermoplastic polymeric materials applied by vapor deposition sources contained in the vapor deposition chamber. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable organic solvent to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free.

  • Patent number: 6766764
    Abstract: An device for depositing a transfer material onto a receiving substrate includes a source of pulsed laser energy, a receiving substrate, and a target substrate. The target substrate comprises a laser transparent support having a back surface and a front surface. The front surface has a coating that comprises a mixture of the transfer material to be deposited and a matrix material. The matrix material is a material that has the property that, when it is exposed to pulsed laser energy, it is more volatile than the transfer material. The source of pulsed laser energy is be positioned in relation to the target substrate so that pulsed laser energy is directed through the back surface of the target substrate and through the laser-transparent support to strike the coating at a defined location with sufficient energy to volatilize the matrix material at the location, causing the coating to desorb from the location and be lifted from the surface of the support.

  • Patent number: 6767589
    Abstract: A composite flywheel rotor includes an annular rim mounted on a hub for high speed rotation in an evacuated flywheel enclosure. A smooth epoxy layer is applied to the rim and is cleaned or maintained clean in preparation for a metal coating on the rim. The rim may be baked in a vacuum furnace to drive off the volitiles and water vapor, and a thin metal coating is applied over the entire rim to retard outgassing from the resin in the flywheel composite rim. The metal coating on flywheel rim is preferably aluminum because aluminum adheres well to epoxy and is economical. The metal coating is deposited on the flywheel rim by physical vapor deposition and may be built up after an initial PVD coating by electroplating. A tough protective polymer is applied over the metal coating to protect metal coating from mechanical damage during handling.

  • Patent number: 6759084
    Abstract: It is important for a CPP GMR read head that it have both high resistance as well as high cross-sectional area. This has been achieved by inserting a NOL (nano-oxide layer) though the middle of one or both of the two non-magnetic conductive layers. A key feature is that the NOL is formed by first depositing the conductive layer to about half its normal thickness. Then a metallic film is deposited thereon to a thickness that is low enough for it to still consist of individual islands. The latter are then fully oxidized without significantly oxidizing the conductive layer on which they lie. The remainder of the conductive layer is then deposited to a thickness sufficient to fully enclose the islands of oxide.

    Abstract: Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil is preferably a freestanding multilayered foil structure made up of alternating layers selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually any environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt the joining materials, which upon cooling will form a strong bond, joining two or more bulk materials.

  • Patent number: 6676988
    Abstract: This invention relates to radioactively coated devices, preferably radioctively coated medical devices. These coated devices are characterized as having a low rate of leaching of the radioisotope from the surface of the coated device and a uniform radioactive coating, and are therefore suitable for use within biological systems. Methods for coating a device with a radioisotope comprising are also disclosed. One method comprises immersing the device within a solution containing a &ggr;, &bgr;+, &agr;, &bgr;− or &egr; (electron capture) emitting radioisotope, then exposing the immersed substrate to tuned vibrational cavitation to produce a coated substrate. A second method involves coating a substrate using electroless plating, and yet a third method involves the use of electroplating a radioisotope onto a substate of interest. With these methods, the coating procedures are followed by baking the coated substrate at a temperature below the recrystallization temperature of the substrate.

  • Patent number: 6673227
    Abstract: The parts are produced by two-component injection molding. Those regions that are to be metallized consist of a first plastic and those regions that are not to be metallized consist of a second plastic. After the entire surface of the parts has been seeded, the seeding is selectively removed with the aid of a solvent in the regions which are not to be metallized. The first plastic is insoluble and the second plastic soluble in the solvent. The selective metallization then takes place by electroless metal deposition and, if appropriate, electrodeposition of metal.
