    摘要： The present invention relates to polycrystalline ultra hard material cutting elements, and more particularly to a method of forming a polycrystalline ultra hard material cutting element with a thicker ultra hard layer than cutting elements formed by prior art methods. In an exemplary embodiment, such a method includes pre-sintering the ultra hard material powder to form an ultra hard material layer that is partially or fully densified prior to HPHT sintering, so that the ultra hard layer is pre-shrunk. This pre-sintering in an exemplary embodiment is achieved by means of a spark plasma process, or in another exemplary embodiment by a microwave sintering process.

    摘要： Embodiments relate to methods of fabricating PCD materials by subjecting a mixture that exhibits a broad diamond particle size distribution to a HPHT process, PCD materials so-formed, and PDCs including a polycrystalline diamond table comprising such PCD materials. In an embodiment, a method includes subjecting a mixture to heat and pressure sufficient to form a PCD material. The mixture comprises a plurality of diamond particles exhibiting a diamond particle size distribution characterized, in part, by a parameter θ that is less than about 1.0, where θ = x 6 · σ , x is the average particle size of the diamond particle size distribution, and σ is the standard deviation of the diamond particle size distribution. In an embodiment, the diamond particle size distribution can be generally modeled by the following equation: CPFT 100 = D n - D S n D L n - D S n , wherein CPFT is the cumulative percent finer than, D is diamond grain size, DL is the largest-sized diamond grain, DS is the smallest-sized diamond grain, and n is a distribution modulus.

    摘要： An improved method for synthesizing superabrasive particles provides high quality industrial superabrasive particles with high yield and a narrow size distribution. The synthesis method can include forming a growth precursor of a substantially homogeneous mixture of raw material and catalyst material or layers of raw material and metal catalyst. The growth precursor can have a layer of adhesive over at least a portion thereof. A plurality of crystalline seeds can be placed in a predetermined pattern on the layer of adhesive. The growth precursor can be maintained at a temperature and pressure at which the superabrasive crystal is thermodynamically stable for a time sufficient for a desired degree of growth. Advantageously, the patterned placement of crystalline seeds and disclosed processes allow for production of various morphologies of synthetic diamonds, including octahedral and cubic diamonds, and improved growth conditions generally. As a result, the grown superabrasive particles typically have a high yield of high quality particles and a narrow distribution of particle sizes.

    摘要： An improved method for controlling nucleation sites during superabrasive particle synthesis can provide high quality industrial superabrasive particles with high yield and a narrow size distribution. The synthesis method can include forming a raw material layer, forming a particulate catalyst layer adjacent the raw material layer, and placing crystalline seeds in a predetermined pattern at least partially in the catalyst layer or raw material layer to form a growth precursor. Alternatively, the raw material and catalyst material can be mixed to form a particulate crystal growth layer and then placing the crystalline seeds in a predetermined pattern in the growth layer. Preferably, seeds can be substantially surrounded by catalyst material. The growth precursor can be maintained at a temperature and pressure at which the superabrasive crystal is thermodynamically stable for a time sufficient for a desired degree of growth. The crystalline seeds can be placed in a predetermined pattern using a template, a transfer sheet, vacuum chuck or similar techniques. The superabrasive particles grown using the described methods typically have a high yield of high quality industrial particles and a narrow distribution of particle sizes.
