    Abstract: Fracture-resistant and self-lubricating wear surfaces are provided. In an implementation, a machine surface that is subject to wear is coated with or is constructed of a metallic nanostructure to resist the wear and to provide fracture-resistant hardness, built-in lubrication, and thermal conductivity for heat-sinking friction. The metallic nanostructured surface may be used, for example, on a face seal, bushing, bearing, thrust member, or hydraulic flow passage of an electric submersible pump. In an implementation, the metallic nanostructured surface is a nanocrystalline alloy including nanograin twins of a body-centered cubic (BCC), face-centered cubic (FCC), or hexagonal closest packed (HCP) metal. The nanostructured alloy may include atoms of copper, silver, gold, iron, nickel, palladium, platinum, rhodium, beryllium, magnesium, titanium, zirconium, or cobalt, and may provide more hardness and lubricity than diamond-like carbon coatings or carbides.

    Abstract: An element is deployed within tubing extending to a downhole tool. The downhole tool includes a hydraulic tool and a valve coupled between the conveyance string and the hydraulic tool. The valve includes a valve seat having a passage directing the fluid from the conveyance string to the hydraulic tool. Deploying the element includes landing the element on the valve seat such that the element substantially obstructs flow of the fluid through the valve seat passage. The valve is opened to direct the flow of the fluid around the hydraulic tool, wherein opening the valve utilizes pressure generated in response to the element obstructing the flow of the fluid through the valve seat passage. At least a portion of at least one of the element and the valve seat is then degraded by an amount sufficient to permit the element to pass through the valve seat passage.

    Abstract: A pressure disintegrable device includes a first volume that further includes a first portion and a second portion. The first portion is adapted to transmit a pressure applied to the first volume to a second portion disposed on the first portion. The second portion is adapted to decrease a melting point thereof as the transmitted pressure increases beyond a predetermined pressure. The pressure disintegrable device may also include a layer disposed on the first volume that is adapted to create a seal between the first volume and an external structure.

    Abstract: An apparatus that is usable within a well includes a string and an object. The object is adapted to be communicated into the well through a passageway of the string to form an obstruction downhole in the well. The object includes an inner core; a layer to surround the inner core; and a structure to extend from the layer to support the inner core while the layer is being formed to position the inner core with respect to the layer.
