    Abstract: The objective of the present invention is to provide an unexpected method of manufacturing a battery electrode and a coating die for use therein, both of which are capable of providing a high speed drying and of improving a peel strength between a collector and a compound. The manufacturing process S1 of manufacturing the battery electrode 1 includes the process of coating the compound 3 containing the electrode active material 4 and the binder 5 on the sheet collector 2 and the process of drying the compound 3 to bond the collector 2 and the compound 3, wherein in the coating process, a laser light is emitted to the interface between the compound 3 and the collector 2. Due to the above structure, regardless of the drying speed, the binder 5 contained in the compound 3 is crystallized at the interface with respect to the collector 2. As a result, the high speed drying is provided and the peel strength between the collector 2 and the compound 3 is improved.

  • Patent number: 8962066
    Abstract: A method of repairing a component removes a prior coating from an underlying metal substrate. Small cooling air holes extend through the substrate and the coating that is to be removed. A new coating layer is placed on the metal substrate, and over the existing cooling air holes. The location of the cooling air holes is identified by inspecting the coated component for the location of indicators of the coating passing over the cooling air holes. The identified location of the indicators is used to control a cutting tool to remove any new coating from the cooling air holes. The basic method may also benefit new manufacture.

  • Publication number: 20140314995
    Abstract: A method of pulsed laser processing of solid surface for enhancing surface hydrophobicity is disclosed wherein the solid surface is covered with a transparent medium during laser processing and the laser beam incidents through the covering medium and irradiates the solid surface. Two effects are obtained simultaneously. One is the laser-induced texture formation directly under the laser irradiation. The other is the deposition of the laser-removed materials along the laser scan lines. Both effects introduce surface roughness on nanometer scales, and both enhance surface hydrophobicity, rendering superhydrophobicity on the surfaces of both the laser-irradiated solid and the covering medium. Because the beam scan line spacing can be larger than a single scan line width by multiple times, this method provides a high processing speed of square inch per minute and enables large area processing.

Additionally, the method may include depositing the alumina and the at least one rare earth oxide from the vapor plume over the surface of the internal cavity to form a calcia-magnesia-alumina-silicate (CMAS)-resistant environmental barrier coating (EBC) comprising the alumina and the at least one rare earth oxide.

  • Publication number: 20140227461
    Abstract: A system and method for multiple beam laser deposition of thin films wherein separate laser beams are used to ablate material from separate targets for concurrent deposition on a common substrate. The laser beams may have the same or different wavelengths, energies, or pulse rates. The targets may be similar or differing classes of materials including, but not limited to polymers, organics, inorganics, nanocrystals, solutions, or mixtures of materials. One or more targets may be disposed on a tiltable mount to adjust the direction and mixing of the ablation plumes from the multiple targets. The target surface may be scanned by moving the target in one or more axes. Multiple ablation modes may be concurrently employed at the various targets, including, but not limited to pulsed laser, MAPLE, IR-MAPLE and other modes. A polymer-nano-composite film example is disclosed.

  • Patent number: 8802185
    Abstract: An object is to provide a deposition method for smoothly obtaining desired pattern shapes of material layers and a method for manufacturing a light-emitting device while throughput is improved when a plurality of different material layers is stacked on a substrate. A material layer is selectively formed in advance in a position overlapped with a light absorption layer over a first substrate by pump feeding. Three kinds of light-emitting layers are deposited on one deposition substrate. This first substrate and a second substrate that is to be a deposition target substrate are arranged to face each other, and the light absorption layer is heated by being irradiated with light, whereby a film is deposited on the second substrate. Three kinds of light-emitting layers can be deposited with positional accuracy by performing only one position alignment before light irradiation.

  • Patent number: 8795794
    Abstract: The present invention concerns the down hole motors used in the oil prospecting industry to drive drill bits for drilling the ground at great depths. The down hole motor (1) comprises a drive shaft (5) held in the motor body (3) by an axial thrust bearing (6) and by a radial bearing (7). The radial bearing (7) is a tubular member whose interior surface is coated with an anti-abrasion layer (11) formed by laser-assisted facing directly inside an alloy steel radial bearing body (10). The thickness of the facing layer is then reduced by removing material by means of a cutting tool. This produces a radial bearing (7) that is relatively insensitive to drilling mud and confers great reliability on the down hole motor (1).

    Abstract: The invention relates to the field of production of barium-scandate dispenser cathodes or other barium-scan-date materials. A target (66) containing a mixture of BaO, CaO, Al2O3 and SC2O3 tends to be more stable, the higher the scandia (scandium oxide) content is. However, an increased scandia content results in a reduced emission capability. A destabilizing effect of BaO and CaO reactions is counteracted by the more inert SC2O3 and also AI2O3 components, as not only an increased scandia content stabilizes the material but also an increased alumina (aluminum oxide) content improves the stability.
