    摘要: A method for testing a shear cutter includes: plunging the shear cutter into a rotating target cylinder by a first depth of cut (DOC) while measuring or controlling a first force exerted on the shear cutter; moving the plunged shear cutter across the rotating target cylinder for a first pass; plunging the shear cutter into the rotating target cylinder by a second DOC while controlling a second force exerted on the shear cutter; and moving the plunged shear cutter across the rotating target cylinder for a second pass. The second force is controlled to be equal to the first force. The second DOC is less than the first DOC.

    摘要: A method for testing thermal fatigue resistance of a shear cutter includes: engaging the shear cutter with a rotating target cylinder; moving the shear cutter along the rotating target cylinder until the shear cutter is heated to a threshold temperature; cooling the shear cutter in response to heating of the shear cutter to the threshold temperature; and repeating the heating and cooling of the shear cutter.

    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.

    摘要: A cleaned component having a polycrystalline structure, a method and apparatus for cleaning a leached component to form the cleaned component, and a method for determining the effectiveness of cleaning the leached component. The cleaned component includes a leached layer that has at least a portion of by-product materials removed. The by-product materials were deposited into the leached layer during a leaching process that formed the leached layer. The apparatus and method for cleaning includes a tank, a cleaning fluid placed within the tank, and at least a portion of the leached layer immersed into the cleaning fluid. Optionally, a transducer emits ultrasonic waves into the leached layer. The method for determining the effectiveness of cleaning includes cleaning the leached component to form the cleaned component, measuring one or more capacitance values of the cleaned component, repeating the cleaning and the measuring until achieving a stable lower limit capacitance value.
