Abstract: Methods of forming a cutting element include sintering diamond particles at a temperature of at least about 1400° C. under a pressure of at least about 10 GPa in the absence of a metal solvent catalyst so as to form a polycrystalline diamond compact (PDC), providing a barrier material over at least a portion of the PDC, providing a carbide material and a metal binder comprising at least one transition metal element over the barrier material and the PDC, and performing a second sintering process comprising sintering the carbide material, the metal binder, the barrier material, and the PDC at a temperature of at least about 1400° C. under a pressure of at least about 5 GPa to form the cutting element. At least a portion of the PDC proximate an exposed exterior surface of the PDC may be at least substantially free of the metal binder.

Abstract: A cutting element comprises a supporting substrate, and a cutting table attached to an end of the supporting substrate. The cutting table comprises a first region and a second region. The first region comprising inter-bonded diamond particles and is substantially free of at least highly catalytic metallic compounds, one or more non-catalytic compounds within interstitial spaces between the inter-bonded diamond particles, and voids within interstitial spaces between the inter-bonded diamond particles. The second region comprising inter-bonded diamond particles, one or more non-catalytic compounds within interstitial spaces between the inter-bonded diamond particles, and one or more metallic phases within interstitial spaces between the inter-bonded diamond particles. The first region of the cutting table has a content of elemental metal of at least about 2.6 wt %. A method of forming a cutting element, and an earth-boring tool are also described.

Abstract: A method of making a cutting element for use on an earth-boring tool may include forming the cutting element including a cutting table formed from a superabrasive polycrystalline material. The method may further include polishing a cutting surface of the cutting table by pulsing a laser onto the cutting surface of the cutting table. The cutting element may include a superabrasive polycrystalline cutting table including a cutting surface substantially free of micro-anomalies in the superabrasive material.

Abstract: A cutting element for downhole drilling and related earth-boring tool for downhole drilling. The cutting element may include a substrate and a polycrystalline diamond material affixed to the substrate at an interface. The polycrystalline diamond material may include a raised cutting surface having at least two cutting edges, and first transition surfaces between the at least two cutting edges of the raised cutting surface and a side surface of the cutting element. The first transition surfaces may include multiple planar surfaces.
