摘要： An evaluation method of abrasive grains used in an ingot-cutting slurry includes: an evaluation solution preparation step in which abrasive grains including polishing grains and impurities are dissolved in a solvent to prepare an evaluation solution; a sedimentation step in which a container containing the evaluation solution is left still to settle the polishing grains; a measurement step in which a turbidity of supernatant of the evaluation solution is measured using the measurement device; and an estimation step in which an amount of the impurities is estimated based on the measurement result of the turbidity of the supernatant.

摘要： A method of characterizing a quality of a polycrystalline diamond compact (PDC) cutter includes obtaining a PDC cutter that includes a leached layer and an unleached layer. The unleached layer is positioned adjacent to the leached layer, and the leached layer has at least a portion of a catalyst material removed from therein. The method further includes measuring capacitance values of the PDC cutter at multiple frequencies of an electrical signal provided to the PDC cutter by a capacitance measuring device to measure the capacitance values of the PDC cutter. The method also includes characterizing a quality of the PDC cutter based on a lowest capacitance value from among the capacitance values. Each capacitance value of the capacitance values is measured at a respective frequency of the multiple frequencies of the electrical signal.

摘要： A method and apparatus are provided for measuring the crushing strength of an abrasive, comprising particles, used in a lapping process. Embodiments include a crushing strength tester having a cup for holding the abrasive; a first motor for rotating the cup in a first direction; a piston having a face for rotatably fitting within the cup and contacting the abrasive; a second motor for rotating the piston in a second direction opposite the first direction; and a press for pressing the piston against the abrasive and crushing the particles while the first and second motors are rotating. An initial particle size distribution for the particles is determined, then the abrasive is subjected to a crushing force approximately equal to that of the lapping process using the crushing strength tester. A post-crushing particle size distribution for the particles is determined, and the initial and post-crushing particle size distributions are compared.

The first wire electrically couples the positive terminal to one of the surfaces of the leached component and the second wire electrically couples the negative terminal to the other surface of the leached component. The capacitance is measured one or more times and compared to a calibration curve to determine an estimated leaching depth within the polycrystalline structure. A data scattering range is ascertained to determine a relative porosity of the polycrystalline structure or the leaching quality within the polycrystalline structure.

摘要： The present disclosure provides methods and techniques for determining wear abrasion resistance of superhard components, such as cutters used in down-hole drilling tools. The methods and techniques provided herein produce an efficiency ratio of a superhard component through data obtained from a vertical turret lathe test. The efficiency ratio is the ratio between the volume of a target cylinder removed by the superhard component during the vertical turret lathe test and the normal force applied onto the superhard component by the target cylinder. The efficiency ratio is indicative of the energy efficiency of the superhard component.

摘要： A method and apparatus for non-destructively determining the wear resistance of an ultra-hard polycrystalline structure after being coupled to a downhole tool using capacitance measurements. The apparatus includes a capacitance measuring device having a positive and negative terminal, a leached component comprising a polycrystalline structure that has been coupled to a downhole tool, a first wire, and a second wire. The first wire electrically couples the positive terminal to a surface of the leached component and the second wire electrically couples the negative terminal to a surface of the downhole tool. The capacitance is measured for the leached component one or more times and compared to a calibration curve that shows a relationship between capacitance values and wear resistance, thereby allowing determination of an estimated wear resistance for the polycrystalline structure.
