摘要： An abrasive tool is provided that may include a body, which may include abrasive particles contained within a bond material. The abrasive particles may be a super abrasive material. The body may further include at least one of a ratio of tungsten to cast iron (W/CI) of not greater than about 1, a ratio of copper-containing compositions to cast iron (CCC/CI) of not greater than about 1, a ratio of titanium-containing compositions to cast-iron (TiCC/CI) of not greater than about 1, a ratio of tungsten carbide to cast iron (WC/CI) of not greater than about 1, a ratio of tungsten carbide to copper-containing compositions (WC/CCC) of not greater than about 1, a ratio of copper-containing compositions and titanium-containing compositions to cast iron ((CCC+TiC)/CI) of not greater than about 1.5 or a combination thereof.

摘要： An abrasive article including a substrate in the form of an elongated member having a core and a barrier layer in direct contact with an peripheral surface of the core. The barrier layer consists essentially of tin. A bonding layer is overlying the elongated substrate and abrasive particles are secured in the bonding layer

摘要： An abrasive article includes an organic bond material, an abrasive material dispersed in the organic bond material, mineral wool microfibers uniformly dispersed in the organic bond material, the mineral wool microfibers being individual filaments, one or more reinforcement and/or chopped strand fibers dispersed in the organic bond material and one or more active fillers including, for example, a manganese compound. The abrasive article can be used in the abrasive processing of a workpiece.

摘要： A method of forming a chemical mechanical planarization (CMP) pad conditioner includes placing abrasive grains on a major surface of a substrate, forming a binding composition at an exterior surface of the abrasive grains, and depositing a bonding layer over the surface of the substrate and a portion of the abrasive grains to secure the abrasive grains to the major surface of the substrate.
