20080284107 | Ceramic Brush Seals - The present invention provides a ceramic brush seal including a plurality of ceramic bristles and a support member supporting the plurality of ceramic bristles. Each of the plurality of ceramic bristles extending from a first end to a second end. The plurality of bristles are bent over the support member such that the first end and the second end form a brushing surface on a side of the support member and a fold on an other side of the support member. The plurality of ceramic bristles is made from a ceramic material selected to operate at temperatures in excess of 1500° F. | 11-20-2008 |
20090072486 | Brush seal - A brush seal for sealing gaps, such as those found in gas turbine engines, includes a plurality of metallic bristles mechanically captured by a support member. The support member includes at least one flexible plate extending at least substantially along the bristle length of the plurality of bristles. The support member is constructed and arranged to support the plurality of metallic bristles during operation. | 03-19-2009 |
20090114543 | ELECTROCOMPOSITE COATINGS FOR HARD CHROME REPLACEMENT - The invention provides a method and system for electrolytically coating an article. The method includes providing an article to be coated and disposing the article in an electrolytic cell. The cell includes an anode, a cathode in operable communication with the article, and an electrolyte bath. During electrolysis, the electrolyte bath comprises cobalt ions, phosphorous acid, and tribological particles selected from the group consisting of refractory materials, solid lubricants and mixtures thereof dispersed therein. The method further includes applying steady direct electric current through the anode, the electrolyte bath and the cathode to coat the article with cobalt, phosphorous and the tribological particles. An improved composition of matter is also provided that may be used as a coating, or the composition may be electroformed on a mandrel to form an article made from the composition of matter. | 05-07-2009 |
20090208775 | PROTECTIVE COATING FOR METALLIC SEALS - A composition and process for forming an electrodeposited coating comprising a co-deposit of a metal and MCrAlY particles. The composition includes a metal and a MCrAlY particles, and the electrodeposited coating comprises a metal matrix and MCrAlY particles dispersed in the matrix. In one aspect, a coating is provided that exhibits excellent oxidation resistance and tribological characteristics at high temperatures, including up to at least about 1350° F. A high temperature coating may comprise a nickel/cobalt alloy matrix comprising MCrAlY particles and chromium carbide particles dispersed in the nickel/cobalt matrix. | 08-20-2009 |
20100096811 | Electro-composite coating for flexible seals and method of applying the same - An electro-composite tribological coating for coating a flexible or compliant structure, for example a structural seal, includes a cobalt and cobalt alloy base containing a fine dispersion of tribologically suitable particles such as chromium carbide (Cr | 04-22-2010 |

20140137831 | Cylinder Bore Coating System - Embodiments of the present innovation relate to a cylinder bore coating system which simultaneously combines both friction and wear properties to enhance engine efficiency and operating life. The cylinder bore coating system includes a relatively thin top layer, such as diamond like carbon layer (DLC), disposed over a thicker, relatively hard and high modulus coating (i.e., an under coating). This combination of layers provides both low friction as well as low wear characteristics to the engine bore, relative to conventional engine bore coatings. | 05-22-2014 |
