| 20120114929 | HIGH PURITY CERAMIC ABRADABLE COATINGS - The invention is directed to a material and method for obtaining a ceramic abradable system for high temperature applications. High purity partially stabilized zirconia and/or hafnia base material has higher sintering resistance compared to conventional 6-9 weight percent yttria stabilized zirconia systems. The benefits of these systems are higher service lifetime and low thermal conductivity to achieve high operating temperatures. System includes a superalloy substrate, oxidation resistant bond coat and a thick ceramic abradable top coat. Total coating thickness is about 0.5-5 mm. In some applications an intermediate layer of high purity partially stabilized zirconia or a partially stabilized YSZ/MCrAlY cermet is applied over the oxidation resistant bond coat. In other applications an abradable system is applied on top of a grid. Additional benefits should be reduced blade wear at high operating conditions. | 05-10-2012 |
| 20110129399 | HIGH PURITY AND FREE FLOWING METAL OXIDES POWDER - A metal oxide powder includes a powder feed material structured and arranged to form molten droplets when melted in a plasma stream. The molten droplets are structured and arranged to form frozen spherical droplets under free-fall conditions such that said molten droplets have ample time for complete in-flight solidification before reaching a collection chamber. | 06-02-2011 |
| 20110045197 | METHOD OF IMPROVING MIXING OF AXIAL INJECTION IN THERMAL SPRAY GUNS - Method for performing a thermal spray process. Method includes heating and/or accelerating a gas to form an effluent gas stream, feeding a particulate-bearing carrier stream through an axial injection port into the effluent gas stream to form a mixed stream, in which the axial injection port includes a plurality of chevrons located at a distal end of said axial injection port, and impacting the mixed stream on a substrate to form a coating. | 02-24-2011 |
| 20110003165 | MULTI-LAYER ANTI-CORROSIVE COATING - A multilayer coating has a first coating layer deposited on a substrate; a second coating layer deposited on the first coating layer; and a third coating layer deposited on the second coating layer. The first coating layer is substantially a metal, the second coating layer is a mixture of the metal and a polymeric material, and the third coating layer is substantially the polymeric material. The substrate is at least one of iron, iron pipe, steel, copper, nickel, concrete, wood, wood products, fiberglass, ceramic, plastic, and any other metal or non-metal material that can be used as a substrate, and the metal is at least one of zinc, aluminum, magnesium, indium, gallium, tellurium, and alloys thereof, whereby the metal used is anodic to the substrate. The polymeric material is at least one of polyethylene, polypropylene, nylon, polytetrafluorethylene (PTFE), ethylene methacrylate acid copolymer (EMAA), a thermoplastic material and a thermoset material. | 01-06-2011 |
| 20100330291 | TWO STAGE KINETIC ENERGY SPRAY DEVICE - A two stage kinetic energy spray device has a first stage first nozzle having a receiving end that receives a particulate stream, an injection end located axially to the first nozzle receiving end, the injection end receiving the particulate stream from the receiving end. A second stage has a second nozzle, the second nozzle having a gas receiving portion that receives an effluent gas, a convergent portion that is downstream from the gas receiving portion and a divergent portion that is downstream from the convergent portion, the convergent portion and the divergent portion meeting at a throat. The particle stream is accelerated to a first velocity in the first nozzle located within the second nozzle divergent portion The effluent gas is accelerated to a second velocity in the second nozzle. First nozzle injection end chevrons allow mixing of particulate and supersonic effluent streams prior to exiting the spray device. | 12-30-2010 |
| 20100323117 | SYMMETRICAL MULTI-PORT POWDER INJECTION RING - Powder injection apparatus, plasma gun, and method of use. Powder injection apparatus includes a shroud attachable to an outlet nozzle of a thermal spray apparatus and a substantially smooth and continuous inner wall defining a bowl through which a plume of the thermal spray apparatus travels. At least one port in the inner wall is structured and arranged to receive a powder injection nozzle that injects powder into the plume. | 12-23-2010 |
| 20100285329 | PROTECTIVE COATINGS AND METHODS OF FORMING SAME - Coatings on a substrate and application methods result in coatings that can withstand different types or groups of bulk cargo and operations. This novel approach includes use of a combination of layers of coating materials at certain thicknesses and applied with certain techniques. In certain embodiments, the coating system includes coatings applied to a pretreated substrate, e.g., blasted steel cargo hold plates of an oceangoing vessel. The coatings include a bond layer and a resistance layer, e.g., an anti-corrosive layer tailored to resist at least one of corrosion, erosion, impact and wear of the substrate. | 11-11-2010 |
| 20100270387 | INTRINSICALLY SAFE VALVE FOR A COMBUSTION SPRAY GUN AND A METHOD OF OPERATION - A valve for a combustion spray gun. An apparatus includes a torsion element rotatable relative to a housing of the combustion spray gun to a charged position. The apparatus also includes a biasing element applying a force to the torsion element, which force urges the torsion element to move a valve core to an off position. The apparatus further includes an engagement mechanism configured to selectively engage and hold the torsion element in the charged position. | 10-28-2010 |
