20200122914 · 2020-04-23 ·

An article includes a package including a packaging material defining an enclosed volume, wherein a desiccant and a bonded abrasive article are contained within the enclosed volume. In an embodiment, the desiccant comprises calcium ions in an amount of at least 7600 ppm of a total weight of the desiccant. In another embodiment, the bonded abrasive article has a moisture uptake of at most 0.3% when exposed to 90% relative humidity at 40 C. for 24 days.

Combined field assisted sintering techniques and HTHP sintering techniques for forming polycrystalline diamond compacts and earth-boring tools

Methods of forming polycrystalline diamond compacts include employing field assisted sintering techniques with high temperature and high pressure sintering techniques. For example, a particle mixture that includes diamond particles may be sintered by subjecting the particle mixture to a high temperature and high pressure sintering cycle, and pulsing direct electrical current through the particle mixture during at least a portion of the high temperature and high pressure sintering cycle. The polycrystalline diamond compacts may be used to form cutting elements for earth-boring tools. Sintering systems are configured to perform such sintering processes.

Cutting tables including rhenium-containing structures, and related cutting elements, earth-boring tools, and methods

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.

Cutting elements including undulating boundaries between catalyst-containing and catalyst-free regions of polycrystalline superabrasive materials and related earth-boring tools and methods

Cutting elements for earth-boring tools may include a substrate and a polycrystalline superabrasive material secured to the substrate. The polycrystalline superabrasive material may include a first region including catalyst material in interstitial spaces among interbonded grains of the polycrystalline superabrasive material. A second region at least substantially free of catalyst material in the interstitial spaces among the interbonded grains of the polycrystalline superabrasive material may be located adjacent to the first region. An undulating boundary defined between the first region and the second region may include bumps and dimples formed by crests and troughs of a repeating pattern of concentric circles encircling a longitudinal axis of the cutting element.
