Abstract: The present disclosure relates to a brazed superabrasive assemblies and method of producing brazed superabrasive assemblies. The brazed superabrasive assemblies may include a plurality of braze alloy layers that are positioned opposite a stress relieving layer. The stress relieving layer may have a solidus temperature that is greater than a solidus temperature of the plurality of braze alloy layers.

Abstract: Ceramic-bonded diamond composite particle includes a plurality of diamond grains and silicon carbide reaction bonded to the diamond grains having a composition of 60-90 wt. % diamond, 10-40 wt. % silicon carbide, ?2 wt. % silicon. Particles are formed by processes that forms granules in a pre-consolidation process, forms a densified compact including ceramic-bonded diamond composite material in a consolidation process or forms ceramic-bonded diamond composite material directly, and a post-consolidation process in which the densified compact or ceramic-bonded diamond composite material is mechanically broken to form a plurality of the particles. Inert or active material can be incorporated into the densified compact or coated on granules to reduce the number and extent of diamond to silicon carbide bonding occurring in the consolidation process and make the ceramic-bonded diamond composite material more friable and easily breakable into composite particles.

Abstract: Multi-part abrasive tools are disclosed herein. In one embodiment, an abrasive tool includes a first body, a second body, and a braze layer that couples the first body to the second body. The braze layer includes a braze alloy having a liquidus temperature and insoluble particles at least partially surrounded by the braze alloy. The insoluble particles are insoluble with the braze alloy at temperatures at least 100° C. above the liquidus temperature of the braze alloy.

Abstract: The present invention relates to a diamond composite comprising diamond particles embedded in a binder matrix comprising SiC and a Mn+1AXn-phase, where no diamond-to-diamond bonding are present. For the Mn+1AXn-phase n=1-3, M is one or more elements selected from the group Sc, Ti, Zr, Hf, V, Nb, Ta, Cr and Mo, A is one or more elements selected from the group Al, Si, P, S, Ga, Ge, As, Cd, In, Sn, Tl, and Pb and X is carbon and/or nitrogen.

Abstract: A tool and a method of making the tool is disclosed. The tool comprises a sleeve and a compact. The sleeve may have a proximal end, a distal end, a central axis, and a bore extending from the proximal end to the distal end, the bore having an inner wall. The compact may have a base end and an impact surface spaced opposite to the base end. The compact may be substantially disposed within the bore of the sleeve. The proximal end may be disposed proximate the base end of the compact.

Abstract: The present disclosure provides a CMP pad conditioning tool with at least one integral abrasive protrusion. The present disclosure further provides a method for preparing this CMP pad conditioning tool, along with a method for using said tool to condition a CMP pad.

Abstract: An abrasive tool insert is formed from a substrate having an inner face that has a center. The inner face slopes outwardly and downwardly from the center. An annular face slopes downwardly and outwardly from the inner face. An abrasive layer, having a center and a periphery forming a cutting edge, is integrally formed on the substrate.
