摘要： A tool such as a wafer handler or wafer chuck can include a surface having at least one protrusion. A diamond coating is formed from diamond grains sized so that 90% of the grains are between 200 and 300 nanometers, with the diamond coating being deposited on the surface at a temperature below 500 degrees Celsius over the at least one protrusion. Dopants can be used to provide electrical conductivity needed for electrostatic wafer chuck.

摘要：高硬質脆性材を高能率で研削することができる高寿命の砥石を提供する。　高硬質脆性材用メタルボンド砥石であるセグメント砥石１４は、セグメント砥石１４全体に対し気孔径が５０から２００μｍの気孔２２が、５０から６５体積％の気孔率で備えられている。このように、直径が５０から２００μｍの気孔径と５０から６５体積％の気孔率とを備えているため、加工抵抗の増大およびメタルボンドの脆性が抑制されるとともに、被削材３０に対する接触面圧を高めることができて適切な研削加工が得られる。また、メタルボンド２０が上記のような気孔２２を備えた有気孔構造であることから、気孔２２がチップポケットとして寄与して研削時の切り屑３２の排出性能や冷却性能が高められるとともに、研削面におけるメタルボンド２０の後退性が高められる。

摘要： The present invention refers to a process for making a grinding wheel for the squaring of ceramic, formed by a support body and an abrasive ring. The process does not involve costly workings on the body and on the ring and allows to obtain a light grinding wheel which, therefore, is more practical to be handled by the handling machine.

摘要： Ultra-hard constructions (10) comprise a polycrystalline diamond-body (12, a first metallic substrate (14) attached thereto, and a second metallic substrate (16) attached to the first metallic substrate (14). The first and second substrates (14, 16) each comprise a first hard particle phase and a second binder material phase, where the hard particles in the second substrate (16) are sized larger than those in the first substrate (14). The first substrate (14) may contain a greater amount of binder material than the second substrate (16). The first substrate (14) facilitates sintering the diamond body (12) during HPHT conditions, and the second substrate (16) provides an improved degree of erosion resistance when placed in an end-use application. The construction may be formed during a single HPHT process. The second substrate (16) may comprise 80 percent or more of the combined thickness of the first and second substrates (14, 16).

摘要： Polycrystalline compacts include a polycrystalline superabrasive material comprising a first plurality of grains of superabrasive material having a first average grain size and a second plurality of grains of superabrasive material having a second average grain size smaller than the first average grain size. The first plurality of grains is dispersed within a substantially continuous matrix of the second plurality of grains. Earth-boring tools may include a body and at least one polycrystalline compact attached thereto. Methods of forming polycrystalline compacts may include coating relatively larger grains of superabrasive material with relatively smaller grains of superabrasive material, forming a green structure comprising the coated grains, and sintering the green structure. Other methods include mixing diamond grains with a catalyst and subjecting the mixture to a pressure greater than about five gigapascals (5.0 GPa) and a temperature greater than about 1,300°C to form a polycrystalline diamond compact.

摘要： Methods of forming a polycrystalline compact using at least one metal salt as a sintering aid. Such methods may include forming a mixture of the at least one metal salt and a plurality of grains of hard material and sintering the mixture to form a hard polycrystalline material. During sintering, the metal salt may melt or react with another compound to form a liquid that acts as a lubricant to promote rearrangement and packing of the grains of hard material. The metal salt may, thus, enable formation of hard polycrystalline material having increased density, abrasion resistance, or strength. The metal salt may also act as a getter to remove impurities (e.g., catalyst material) during sintering. The methods may also be employed to form cutting elements and earth-boring tools.
