Abstract

A cemented tungsten carbide body is formed by mixing a tungsten carbide powder and a cobalt powder together to form a powder mixture. The tungsten carbide powder makes up greater than or equal to 80 weight percent of the powder mixture, while the cobalt binder powder makes up about 1.5 weight percent to about 20 weight percent of the powder mixture. Next, the powder mixture is compacted to form a green compact, and a boron nitride coating is applied to a surface of the green compact to form a coated compact. The coated compact is sintered at a temperature sufficient to melt the cobalt powder, such that boron from the boron nitride coating diffuses into the compact and creates a gradient of metallic cobalt and boron extending inward from the surface. The metallic cobalt content increases from the surface inward, while the boron content decreases from the surface inward.

Abstract

A cubic boron nitride particle population having highly-etched surfaces and a high toughness index is produced by blending a reactive metal powder with a plurality of cubic boron nitride particles to form a blended mixture. The blended mixture is compressed to form a compressed mixture. The compressed mixture is subjected to a temperature and a pressure, where the temperature is controlled to cause etching of the plurality of cubic boron nitride particles by reaction of cubic boron nitride with the reactive metal powder, thereby forming a plurality of etched cubic boron nitride particles. Also, the temperature and pressure are controlled to cause boron nitride to remain in a cubic boron nitride phase. Afterwards, the plurality of etched cubic boron nitride particles is recovered from the compressed mixture to form the particle population. Preferably, the particle population contains no hexagonal boron nitride.

Abstract

Diamond bodies and methods of manufacture are disclosed. Diamond bodies are formed from at least a bimodal, alternatively a tri-modal or higher modal, feedstock having at least one fraction of modified diamond particles with a fine particle size (0.5-3.0 μm) and at least one fraction of diamond particles with coarse particle size (15.0 to 30 μm). During high pressure—high temperature processing, fine particle sized, modified diamond particles in the first fraction preferentially fracture to smaller sizes while preserving the morphology of coarse particle sized diamond particles in the second fraction. Diamond bodies incorporating the two fractions have a microstructure including second fraction diamond particles dispersed in a continuous matrix of first fraction modified diamond particles and exhibit improved wear characteristics, particularly for wear associated with drilling of geological formations.

Abstract

Multi-step milling processes to prepare cBN composite powder forms a first powder mixture by adding a binder and a first cBN component, mills the first powder mixture for a first time period, combines a second cBN component with the milled first powder mixture to form a second powder mixture, and mills the second powder mixture for a second time period (less than the first time period) to form the cBN composite powder. A ratio of the D50 value of the second cBN component to the D50 value of the first cBN component is at least 3.0. Two-step milling with different milling times for the two cBN component fractions controls the amount of mill debris in the cBN composite powder mixture. Further processing of the cBN composite powder under HPHT conditions forms a cBN-based ceramic with an average value of a cBN particle free diameter of less than 2.0 microns.

Abstract

A method of treating a polycrystalline diamond (PCD) compact including a substrate and a layer of diamond material mixture of diamond particles and binder-catalyst disposed on the substrate. A leaching agent is applied to at least the layer of diamond material of the PCD compact. The leaching agent and a surface of the layer of diamond material are heated to a first temperature. The substrate is cooled to a second temperature. A first temperature gradient is established within the PCD compact to cause an inward diffusion of the leaching agent into at least the layer of diamond material. The cooling of the substrate is stopped and energy is applied directly to the PCD compact to heat the same to a third temperature. A second temperature gradient is established within the PCD compact to cause an outward diffusion of the binder-catalyst to remove the same from the layer of diamond material. The first and second temperature gradients can be repeated to accelerate removal of the reacted binder-catalyst from at least the layer of diamond material.

Abstract

A cutting element include a substrate and a diamond compact including at least two polycrystalline diamond portions separated by at least one metal carbide foil portion. The cutting element is made by placing diamond powder in a reaction container, placing a thin metal layer in the reaction container above or around the diamond powder and binder, placing additional diamond powder in the reaction container above or around the thin metal layer, and placing a pre-sintered substrate containing binder into the reaction container above all diamond powder and thin metal layer components. The assembled reaction container is put into a reactor and is subjected to a high-temperature high-pressure sintering process. The binder in the pre-sintered substrate sweeps through to sinter the first diamond portion, and then reacts with the thin metal layer to form a metal carbide, and then the binder continues to sweep through to sinter the second diamond portion.

Abstract

A polycrystalline diamond compact (PDC) is fabricated using a process of delayed diffusion of a diffusion species (e.g., a metalloid) introduced from the back side of a cemented carbide further away from the diamond grit or from the flank side of the cemented carbide, as opposed to the side of the cemented carbide adjacent to the diamond grit. The process of fabricating the PDC includes depositing, in a metal container, a diamond grit, a cemented carbide, and a diffusion species, then applying a high pressure and high temperature (HPHT) to the contents of the metal container wherein (1) the binder of cemented carbide diffuses across the diamond grit, and (2) the diffusion species diffuses through the cemented carbide, and then through the diamond grit, thus providing a protective coating to the diamond grains of the PDC.

Abstract

A method for bonding together components, such as a tip and a shaft which include mutually facing carbide end surfaces. The tip includes circumferentially spaced flutes formed in its cylindrical outer periphery. The shaft has a cylindrical outer periphery and a plurality of coolant holes extending through the shaft. Bonding of the tip to the shaft is performed by inserting gauge wires into the coolant holes and associated flutes, and positioning brazing material between the first and second end surfaces. A water-soluble bond-blocking material is applied to the gauge wires for preventing brazing of the gauge wires to the brazing material. The brazing material is heated to braze the first and second end surfaces together while the flutes and their associated coolant holes are maintained in alignment by the gauge wires. Then, the gauge wires are removed, and residual bond-blocking material is dissolved in water.
