    摘要： Methods of coupling a bearing assembly to a downhole tool include forming at least a portion of a downhole component from a diamond-enhanced material, applying a metal material to a surface of the downhole component using an ultrasonic molten metal process, and coupling at least a portion of the surface of the downhole component to at least another component of the downhole tool. Downhole tools include at least one component of a bearing assembly that is configured to move relative to a portion of the downhole tool. The at least one bearing component comprises a diamond-enhanced material and is coupled to a portion of the downhole tool by an ultrasonic molten metal process.

    摘要： Earth-boring casing shoes include a crown configured for at least one of drilling and reaming a wellbore when the crown is attached to a section of casing and the casing is advanced into a wellbore. The crown includes a body comprising a corrodible composite material, and at least one cutting structure carried on the body. The casing shoes further include connection structure configured for attachment to a section of casing. Methods are used to form such casing shoes, and such casing shoes are used to install casing within wellbores.

    摘要： A shrink-fit sleeve assembly comprising a bit body includes at least one sleeve port with a substantially tubular sleeve disposed therein and interferingly engaged therewith. The sleeve port includes an internal surface of substantially circular cross-section, and the tubular sleeve includes an internal nozzle port and an external surface of substantially circular cross-section. A lateral dimension of an external surface is equal to or greater than a first dimension at ambient temperature. A nozzle assembly and a method of manufacturing or retrofitting a drill bit are also disclosed.
