摘要： 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.

摘要： A non-contacting seal for sealing in high temperature applications includes at least one segment having an inner pad with a hydrodynamic/hydrostatic lift-off geometry enabling the seal to run in a non-contact mode, and at least one finger spring supported on the pad that aids in making the seal radially compliant while also being axially stiff, compared to the radial direction. In one embodiment, multiple segments are supported on a support member spaced from the pad to form a gap (g) therebetween. The pad preferably includes a wear resistant layer on its inner diameter (ID) which prevents excessive wear of the pad. In one embodiment, the hydrodynamic/hydrostatic lift-off geometry is in the form of a groove formed on the inner pad. A cover may also be provided between inner pads at the ID and the support ring at the outer diameter OD in order to prevent leakage through the gap.

摘要： An iron based, boron, silicon, carbon and chromium containing magnetic alloy having at least 85 percent of its structure in the form of an amorphous metal matrix is annealed at a temperature and for a time sufficient to induce precipitation therein of discrete particles of its constituents and to form an oxide layer on the surface of the matrix. The resulting alloy has decreased high frequency core losses and increased low field permeability; it is particularly suited for high frequency applications.

摘要： A seal assembly includes a first plate or member having a recess with a bottom mating surface which receives sealing ring therein and a second plate or member having a sealing surface for contacting a metallic sealing ring. First and second plates or members are coupled together by a plurality of fasteners or bolts. By tightening the fasteners the sealing ring is loaded, and thus, compressed to plastically deform and create an annular seal between the first and second members. Metallic sealing ring has a first annular sealing surface, a second annular sealing surface, an annular inner surface and an annular outer surface. The first annular sealing surface faces in a first axial direction to contact sealing surface of first member for creating a first annular sealing dam therebetween. The second annular sealing surface faces in a second axial direction, which is opposite to the first axial direction of the annular sealing surface, to contact sealing surface of second member for creating a second annular sealing dam therebetween. Preferably, the first and second annular sealing surfaces are substantially flat surfaces which are parallel to one another. An annular column section is formed between the first and second annular surfaces. The minimum radial width of the annular column determines the force necessary to deform the sealing ring to its sealing position. A pair of beam sections extend substantially perpendicular to the column section to create the sealing surfaces. At least one brace extends diagonally between the column section and one of the between sections to obtain proper sealing during compression of the sealing ring.
