Abstract

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.
