Abstract
Metal-based ceramic composite coatings and related devices, assemblies, and methods include monocrystalline superhard particles dispersed in a metal matrix disposed on at least one wear surface of a component of an oil and gas well assembly, system, or device.
Claims19
An assembly for an oil and gas well system, the assembly comprising:
- a first component having a first wear surface;
- a second component having a second wear surface that at least partially contacts the first wear surface of the first component during relative movement between the first component and the second component;
- and
- a first metal-based ceramic composite coating defining a contact portion of the first wear surface of the first component that is configured to contact the second wear surface of the second component, the first metal-based ceramic composite coating comprising first monocrystalline superhard particles dispersed in a first metal matrix, the contact portion of the first wear surface including the first monocrystalline superhard particles, wherein the first metal-based ceramic composite coating is polished at the contact portion of the first wear surface, wherein the polished contact portion of the first wear surface of the first metal-based ceramic composite coating is formed by sliding one or more ceramic elements comprising a superhard material having a blunt polishing surface over or within the contact surface in more than one type of relative motion, the more than one type of relative motion comprising at least translation and rotation, wherein the polishing of the polished contact portion is configured to provide a relatively reduced friction coefficient of the polished contact portion and configured to reduce surface roughness of the polished contact portion.

A component for use in an oil and gas well system, the component comprising:
- an element having a wear surface configured to move relative to and at least partially contact another component of an oil and gas well pumping assembly;
- and
- a metal-based ceramic composite plating defining an exposed portion of the wear surface, the metal-based ceramic composite plating comprising superhard monocrystalline particles dispersed in a metal matrix, the exposed portion of the metal-based ceramic composite coating exhibiting a polished surface, the polished surface of the metal-based ceramic composite coating being formed by sliding a ceramic material having a blunt surface on the metal-based ceramic composite coating in more than one type of relative motion, the more than one type of relative motion comprising at least translation and rotation, wherein the forming of the polished surface is configured to provide a relatively reduced friction coefficient of the polished surface and configured to reduce surface roughness of the polished surface.
An assembly for an oil and gas well system, the assembly comprising:
- a first component comprising a plunger having a first wear surface;
- a second component comprising a barrel having a second wear surface that at least partially contacts the first wear surface of the first component during relative movement between the first component and the second component;
- and
- a metal-based ceramic composite coating defining the first wear surface of the plunger and the second wear surface of the barrel, the metal-based ceramic composite coating comprising monocrystalline superhard particles dispersed in a metal matrix, wherein the monocrystalline superhard particles of the first wear surface are the same as the monocrystalline superhard particles of the second wear surface, and wherein the metal matrix of the first wear surface of the plunger comprises a first hardness that is less than a second hardness of the metal matrix of the second wear surface of the barrel, wherein the metal-based ceramic composite coating exhibits a multi-directionally honed surface, the multi-directionally honed surface configured to provide a relatively reduced friction coefficient and configured to provide reduced surface roughness.
