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. |
