    摘要： The disclosed embodiments relate to a valve assembly that includes a valve body that has a cavity having one or more seating surfaces, a ball body disposed within the valve body and configured to engage the one or more seating surfaces to form a seal, and an actuator configured to drive the ball body in a first axial direction along a central axis of the cavity to wedge the ball body against the one or more seating surfaces to form the seal, and where the actuator is configured to move the ball body in a second axial direction along the central axis to unseat the ball body and to rotate the ball body about the central axis between an open position and a closed position.

    摘要： The disclosure provides for a valve including a surface movably engaged with another surface. A coating is on the surface and is characterized by: a CoF of less than 0.1; a hardness in excess of 1,200 HVN; impermeability to liquids at pressures ranging from 15 and 20,000 psi; a surface finish of 63 or less; and a thickness ranging from 0.5 to 20 mils. The disclosure provides for material constructions including a continuous phase, including a transition metal, and a discontinuous phase, including a solid dry lubricant. The disclosure also provides for a method of depositing a coating that includes depositing a first layer of a coating onto a surface using electroplating, electroless plating, thermal spraying, or cladding, and then depositing a second layer of the coating onto a surface of the first layer using sputtering, ion beam, plasma enhanced chemical vapor deposition, cathodic arc, or chemical vapor deposition.

    摘要： The disclosure provides for apparatus, including coated parts, where a base material of the part is coated with a multilayer coating. The multilayer coating includes at least three layers, including at least two electrically conductive layers. Also provided is a method for making apparatus, which includes providing a part and applying a multilayer coating to the base material of the part. Further provided is a method of monitoring and diagnosing a condition of a coated part. The method includes providing a coated part having a multilayer coating on a base material, measuring an electrical response of the multilayer coating, and correlating the electrical response with a condition of the multilayer coating.
