| 20090304942 | WIRE-ARC SPRAYING OF A ZINC-NICKEL COATING - A zinc-nickel substrate is applied to a component by using a zinc-nickel wire formed with between about 8 to 20 percent nickel and between about 80 to 90 percent zinc. This formed zinc-nickel wire is held in a two wire electric arc spray system to spray the zinc-nickel substrate on the component, such as an aircraft part, while operating the two wire electric arc spray system within a specific range of operating parameters. | 12-10-2009 |
| 20110171393 | WIRE ARC SPRAY SYSTEM USING COMPOSITE WIRE FOR POROUS COATING, AND RELATED METHOD - A wire arc spray system use at least one first wire and second wire that include a composite wire including a first material at a core region thereof and a cladding including a second material surrounding the core region. A controller controls operation to propel heated material created by the arcing of the first wire and the second wire at the arc point to a surface to be coated. A wire arc spray methodology for creating a porous metal coating with all-metal wires is also provided. | 07-14-2011 |
| 20120321812 | PROCESS FOR FORMING POROUS METAL COATING ON SURFACES - Embodiments of the invention provide a thermal spray method of forming a protective and porous coating over desired surfaces. Further, embodiments provide a thermal arc spray method, such as twin wire arc spray, to coat the surfaces. The invention may refer to using Aluminium and Silicon alloy in a twin wire arc spray method, to create sacrificial and protective coatings on the surfaces, such as substrates and machine parts. Machine parts may be, for example, of sputtering system. The method may utilize a predefined range of Silicon to be alloyed with Aluminium to improve the physical properties of the Aluminium, and further avoid damages to the coated surface, such as de-lamination and flaking of the coatings and coated surfaces. Additionally, generation of defects during a sputtering process may be efficiently reduced. | 12-20-2012 |
| 20130129931 | ARC SPRAY METHOD FOR MANUFACTURING A DENSE LAYER - An arc spray method is proposed for manufacturing a dense layer on a substrate in which an electric voltage is applied to two electrically conductive spray wires and with which an arc is ignited between the spray wires, wherein a melt is generated from the spray wires in a melting region, with the melt being acted on by a fluid which transports the melt to the substrate where the melt is deposited for generating the layer. Oxidizable particles are supplied to the melt and are deposited on the substrate together with the melt; and after the end of the spraying, the oxidizable particles are at least partly oxidized to densify the layer. | 05-23-2013 |
| 20140154422 | PLASMA SPRAYING PROCESS - The application relates to a process for producing a coating by thermal spraying, in particular by plasma spraying, in which a component, in particular a cylinder liner, is internally coated with an alloy, wherein a plasma nozzle, to which a plasma gas and a transporting gas are fed, rotates about a wire and is movable along a longitudinal axis of the bore, such that the bore is coated as seen from the inside all around and in the axial direction of the bore. What is proposed is a variable gas stream or a variable flow rate of the transporting gas and/or of the plasma gas, it being possible for the flow rate to be set over the axial length (x) of the bore to be coated. | 06-05-2014 |
| 20140186540 | PLASMA SPRAYING PROCESS - The application relates to a process for producing a coating by thermal spraying, in particular by plasma spraying, in which a component, in particular a cylinder liner, is internally coated with an alloy. It is proposed that nitrogen is fed as transporting gas, a spraying additive being a solid alloy wire which is guided into a plasma stream, and coating being performed without additional powder. | 07-03-2014 |
| 20150132501 | METHOD OF PRODUCING PLUG FOR PIERCING-ROLLING - A method for producing a plug for use in a piercing rolling mill for producing a seamless steel tube/pipe includes an arc-spraying step of melting iron wires, and spraying molten material thereof onto a surface of a base metal of a plug by use of an arc-spray gun, so as to form a film containing oxide and Fe on the surface of the base metal of the plug. In the arc-spraying step, the surface of the base metal of the plug is divided into plural sections along an axial direction of the plug, and in turn, the arc-spraying is separately carried out in each of the plural sections while an intersection angle between the center line of a spraying stream from the arc-spray gun and the surface of the plug base metal is maintained within a range of 35 degrees to 90 degrees. | 05-14-2015 |
| 20150376759 | DEVICE FOR THERMALLY COATING A SURFACE - The invention relates to a device for thermally coating a surface, which has at least one housing, a cathode, which is designed as a consumable wire and at least one insulation element, wherein the housing has a non-detachable anti-adhesion layer. | 12-31-2015 |
| 20150376761 | SYSTEMS AND METHODS FOR PLASMA SPRAY COATING - The present disclosure relates to a method for plasma spraying. In one embodiment, a method includes controlling application of a filament embedded with powder particles to a plasma jet to generate a spray for coating a substrate. The method for plasma spraying can include controlling a plasma source to generate a plasma jet, such that the spray is formed by powder that is plasticized and output by the plasma jet to the substrate. | 12-31-2015 |
