A cutting element comprises a supporting substrate, a cutting table comprising a hard material attached to the supporting substrate, and a fluid flow pathway extending through the supporting substrate and the cutting table. The fluid flow pathway is configured to direct fluid delivered to an outermost boundary of the supporting substrate through internal regions of the supporting substrate and the cutting table. A method of forming a cutting element and an earth-boring tool are also described.

Methods of forming cutting elements

An instrumented cutting element, an earth-boring drilling tool, and related methods are disclosed. The instrumented cutting element may include a substrate base, a diamond table disposed on the substrate base, a sensor disposed within the diamond table, a lead wire coupled to the sensor and disposed within a side trench formed within the substrate base, and a filler material disposed within the side trench. The earth-boring drilling tool may include securing the instrumented cutting element to a blade of a bit body. A related method may include forming the instrumented cutting element and earth-boring drilling tool.

Apparatuses and methods for forming an instrumented cutting for an earth-boring drilling tool

Methods of forming earth-boring tools including one or more instrumented cutting elements may involve placing a cutting element partially within a pocket extending into a body of an earth-boring tool. The cutting element may include a first hole extending partially through a cutting element from a back side of the cutting element toward a cutting face and a second, shorter, wider hole extending partially through the cutting element from the back side toward the cutting face. The second hole may be in fluid communication with the first hole. An extension including a passageway extending through the extension may be located at least partially within the second hole, such that the passageway may be in fluid communication with the first hole. A thermocouple may be inserted through the passageway and into the first hole after affixing the cutting element in the pocket.

A cutting table comprises a polycrystalline hard material and at least one rhenium-containing structure within the polycrystalline hard material and comprising greater than or equal to about 10 weight percent rhenium. A cutting element, an earth-boring tool, and method of forming a cutting element are also described.

A method of forming an impregnated cutting structure for an earth-boring tool comprises providing a powder mixture comprising diamond particles and a metal binder in a press and subjecting the powder mixture to a pressure greater than about 4.0 GPa and a temperature greater than about 1,200&#xb0; C. to densify the powder mixture and form an impregnated cutting structure comprising the diamond particles dispersed in a continuous phase comprising the metal binder, wherein the impregnated cutting structure is substantially free of diamond-to-diamond bonds and of carbides.

A method of forming a cutting element comprises disposing diamond particles in a container and disposing a metal powder on a side of the diamond particles. The diamond particles and the metal powder are sintered so as to form a polycrystalline diamond material and a low-carbon steel material comprising less than 0.02 weight percent carbon and comprising an intermetallic precipitate on a side of the polycrystalline diamond material. Related cutting elements and earth-boring tools are also disclosed.

A method of modifying surfaces of diamond particles comprises forming spinodal alloy coatings over discrete diamond particles, thermally treating the spinodal alloy coatings to form modified coatings each independently exhibiting a reactive metal phase and a substantially non-reactive metal phase, and etching surfaces of the discrete diamond particles with at least one reactive metal of the reactive metal phase of the modified coatings. Diamond particles and earth-boring tools are also described.

A method of forming a polycrystalline diamond compact comprises providing metallized diamond particles including diamond particles including nanograins of a sweep catalyst secured thereto, the sweep catalyst comprising at least one of tungsten and tungsten carbide and constituting between about 0.01 weight percent and about 1.0 weight percent of the metallized diamond particles and placing the metallized diamond particles and a metal solvent catalyst in a container. The metallized diamond particles are subjected to a high-temperature, high-pressure process in the presence of the metal solvent catalyst to form a polycrystalline diamond material having inter-bonded diamond grains and nanograins of tungsten carbide, the nanograins of tungsten carbide covering less than about twenty percent of a surface area of the inter-bonded diamond grains. Polycrystalline diamond compacts and earth-boring tools including the polycrystalline diamond compacts are also disclosed.
