Abstract: In an embodiment, a method of fabricating a polycrystalline diamond compact (“PDC”) includes forming a polycrystalline diamond (“PCD”) table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table includes bonded diamond grains defining interstitial regions, with the metal-solvent catalyst disposed therein.

The first infiltrant includes a low viscosity cobalt-based and/or nickel-based alloy infiltrant.

Abstract: Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a pre-determined coating pattern. All three components are generally in registration with each other, thereby providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.
