    Abstract: In an embodiment, a bearing assembly includes superhard bearing elements distributed circumferentially about an axis. At least one of the superhard bearing elements may include a first arcuate end portion, a second arcuate end portion, a first substantially planar face, a second substantially planar face, and a bearing surface. The first and second arcuate end portions may be generally opposite each other. The first substantially planar face may extend between the first and second arcuate end portions. The second substantially planar face may be generally opposite the first substantially planar face. The first substantially planar face may have a length greater than a length of the second substantially planar face. The bearing surface may extend between the first arcuate end portion, the second arcuate end portion, the first substantially planar face, and the second substantially planar face. The bearing assembly includes a support ring that carries the superhard bearing elements.

    Abstract: The invention relates to a turbo-machine (1), comprising a flow channel (5) for a working fluid (A). Said flow channel is delimited by a channel wall (15) with a surface structure (47) that is resistant to wetting by the working fluid (A).The invention also relates to a turbine blade comprising a blade surface (39) which can be subjected to the action of a working fluid (A). Said blade surface has a surface structure which specifically uses the Lotus effect and is resistant to wetting by the working fluid (A); at least in parts.

    Abstract: Diamond surfaces for electric submersible pump (ESP) components are provided. A layer of diamond is deposited, adhered, or sintered directly or indirectly to component surfaces subject to wear, erosion, or abrasion to form at least a partial coating. The diamond surfaces increase longevity and reliability of the ESP by reducing friction, wear, and operating temperature. The diamond surfaces may take several forms, such as an amorphous diamond layer, a polycrystalline diamond (PCD) layer, or a thermally stable polycrystalline (TSP) diamond layer. Diamond surfaces may be used to protect bearings, thrust washers, shafts, sliding surfaces, wet areas, hydraulic flow surfaces in cavities, fluid intake ports, downthrust and upthrust pads, bearing runners, shaft seals, face-seals, hydraulic seals, clearance seals, and other surfaces susceptible to erosion or abrasion in the ESP.

    Abstract: A gamma prime nickel-base superalloy and components formed therefrom that exhibit improved high-temperature dwell capabilities, including creep and dwell fatigue crack growth behavior. The superalloy contains, by weight, 10.00 to 22.0% cobalt, 10.0 to 14.0% chromium, 4.0 to 6.0% tantalum, 2.0 to 4.0% aluminum, 2.0 to 6.0%) titanium, 1.5 to 5.0% tungsten, 1.5 to 5.0% molybdenum, 1.0 to 3.5% niobium, 0.05 to 0.6% hafnium, 0.02 to 0.10% carbon, 0.01 to 0.40 % boron, 0.02 to 0.10% zirconium, the balance essentially nickel and impurities, wherein the titanium: aluminum weight ratio is 0.7 to 1.5. The superalloy is hot worked and heat treated to contain cellular gamma prime precipitates that distort grain boundaries, creating tortuous grain boundary fracture paths that are believed to promote the fatigue crack growth resistance of the superalloy.
