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.
Claims22
A method of producing a metal-based ceramic composite coating on at least a portion of a wear surface of a component for use in an oil and gas well system, the method comprising:
- positioning the at least a portion of the wear surface of the component in a metal plating bath comprising monocrystalline superhard particles in a metallic matrix;
- coating the at least a portion of the wear surface of the component with a coating comprising the monocrystalline superhard particles and the metallic matrix;
- removing the component from the metal plating bath;
- and
- heat treating the at least a portion of the wear surface of the component.
A method of producing a metal-based ceramic composite coating on at least a portion of a wear surface of a component for use in an oil and gas well system, the method comprising:
- positioning the at least a portion of the wear surface of the component in a metal plating bath comprising monocrystalline superhard particles in a metallic matrix;
- coating the at least a portion of the wear surface of the component with a coating comprising the monocrystalline superhard particles and the metallic matrix;
- removing the component from the metal plating bath;
- and
- polishing the at least a portion of the wear surface of the component.
A method of producing a metal-based ceramic composite coating on at least a portion of a wear surface of a component for use in an oil and gas well system:
- forming a metal-based ceramic composite plating on at least a portion of a wear surface of an element configured to move relative to and at least partially contact another component of the oil and gas well system;
- and
- selecting the metal-based ceramic composite plating to comprising superhard monocrystalline particles dispersed in a metal matrix.
