  • Patent number: 9276267
    Abstract: A cathode of a solid-oxide fuel cell includes a first ionic conducting layer, a second layer deposited over the first layer and formed from a mixed ionic and electronic conductor layer including an oxygen ion conducting phase, and a third layer deposited over the second layer and formed from a mixed ionic and electronic conductor layer. A sintering aid and pore formers are added to the second layer and the third layer to establish ionic, electronic, and gas diffusion paths that are contiguous. By adjusting the microstructure of the second and the third layer, a high performance low resistance cathode is formed that bonds well to the electrolyte, is highly electro-catalytic, and has a relatively low overall resistance. By using inexpensive and readily available substances as sintering aid and as pore formers, a low-cost cathode is provided.

  • Publication number: 20070074656
    Abstract: An improved kinetic spray nozzle system design is disclosed. The nozzle includes an improved powder injector having an injector tube and a sleeve wherein the injector tube is received in the sleeve and secured to the sleeve. The powder injector further includes an air gap defined between an inner diameter of the sleeve and an outer diameter of the injector tube wherein the air gap is from 50 to 200 microns. The improved injector is capable of spraying a variety of powder materials including hard and “gummy” powders for without clogging for extended periods of time whereas under similar spray conditions previous designs became completely plugged within minutes. The improved injector design enabled the use of higher main gas temperatures to achieve improved coating formation and deposition efficiencies.

  • Publication number: 20070029370
    Abstract: The present invention is directed to a process for preparing substrates, such as aluminum and aluminum alloy surfaces in heat exchangers, for brazing by depositing thereon a kinetic sprayed brazing composition. The process simultaneously deposits composite particles that include all braze materials, i.e., both filler alloy and brazing flux, and corrosion protection materials used in the brazing of aluminum fins to plates and tubes in a single stage.

  • Publication number: 20060272909
    Abstract: A brake assembly is provided that includes a wear-resistant surface, or a surface prone to corrosion, wherein the surface is coated with a coating that optimizes wear-resistance, corrosion-resistance, adhesiveness, and friction factors of the coating. The coating includes a sacrificial corrosion constituent and a second constituent that is relatively harder than the sacrificial corrosion constituent wherein typical metals often employed as sacrificial anodes for example are contemplated. These include aluminum, zinc, and alloys thereof. The second constituent is potentially formed from a carbide, nitride, oxide, transitional metals and alloys thereof, and mixtures thereof.

  • Publication number: 20060275554
    Abstract: A nozzle assembly for a kinetic spray system includes a convergent portion, a throat portion, and a divergent portion, each cooperating together to define a passage therethrough for passing a mixture of powder particles suspended in a flow of a high pressure heated gas. The nozzle assembly further includes an extension portion attached to the divergent portion and extending to a distal end a pre-determined length from the divergent portion of the nozzle assembly. The extension portion permits a dragging force exerted on the powder particles by the flow of high pressure heated gas to act upon the powder particles for a longer duration of time, thereby permitting the powder particles to accelerate to a greater velocity than has been previously achievable.

  • Publication number: 20060040048
    Abstract: An improved kinetic spray system and a method for using the same in a high speed manufacturing environment are disclosed. The improved kinetic spray nozzle system comprises: a gas/powder exchange chamber connected to a first end of a powder/gas conditioning chamber having a length along a longitudinal axis of equal to or greater than 20 millimeters; a converging diverging supersonic nozzle, the supersonic nozzle having a converging section separated from a diverging section by a throat, the diverging section comprising a first portion and a second portion, with the first portion having a cross-sectional area that increases along a length of the first portion and with the second portion having a substantially constant cross-sectional area along a length of the second portion; and the converging section connected to a second end of the powder/gas conditioning chamber opposite the first end.

  • Publication number: 20050214474
    Abstract: An improved kinetic spray nozzle system is disclosed in addition to improved methods for injection particle powders into a nozzle. Utilization of the nozzle enables one to dramatically increase the deposition efficiency of a variety of particles using a kinetic process. The improved nozzle includes a powder/gas conditioning chamber that increases the particle residence time within the nozzle enabling one to achieve higher particle temperatures prior to their acceleration in the supersonic portion of the kinetic spray nozzle.

  • Publication number: 20050161532
    Abstract: A modified high efficiency kinetic spray nozzle is disclosed. The modified nozzle has a rapid expansion rate in the diverging region relative to prior art nozzles, which enables one to achieve much higher particle velocities without an increase in the main gas temperature. Preferably, the expansion rate of the supersonic nozzle in a portion of the diverging region is at least 1 mm2 per millimeter, more preferably 2 mm2 per millimeter, more preferably 5 mm2 per mm, with a most preferable expansion rate being 10 mm2 per millimeter.

  • Publication number: 20050087587
    Abstract: A method is disclosed for direct application of a brazing flux material to a brazing surface. The method includes the step of applying a brazing filler material to a substrate utilizing a kinetic spray process to form a brazing surface. Following application of the brazing filler material to the substrate brazing flux material can be directly applied to the brazing surface as either a dry powder or a wet slurry. The nature of the brazing surface allows the applied flux material to adhere to the surface without the utilization of additional binders or resin materials.

  • Publication number: 20050085030
    Abstract: Disclosed is a method for forming a heat sink laminate and a heat sink laminate formed by the method. In the method a particle mixture is formed from a metal, an alloy or mixtures thereof with a ceramic or mixture of ceramics. The mixture is kinetically sprayed onto a first side of a dielectric material to form a metal matrix composite layer. The second side of the dielectric material is thermally coupled to a heat sink baseplate, thereby forming the heat sink laminate.

  • Publication number: 20050040260
    Abstract: A new gas collimator for use in a kinetic spray system is disclosed. The collimator reduces turbulence of the main gas and results in significant increases in the amount of particles deposited on a substrate using the system. Kinetic spray nozzles incorporating the new collimator also have significantly higher deposition efficiencies. The new collimator enables the main gas temperature to be reduced while permitting much higher depositions and deposition efficiencies compared to the prior art collimator. Also disclosed is a low pressure injection method for a kinetic spray system. The coaxial, low pressure injection method enables the use of low pressure powder feeders, which are low cost, technologically mature, and widely available commercially. The coaxial injection method overcomes several undesirable effects associated with prior art high pressure injection methods.
