摘要： A method of constructing an earth-boring, diamond-impregnated drill bit has a first step of coating diamond grit with tungsten to create tungsten-coated diamond particles. These coated particles are then encapsulated in a layer of carbide powder held by an organic green binder material. The encapsulated granules are then mixed along with a matrix material and placed in a mold. The matrix material includes a matrix binder and abrasive particles. The mixture is heated in the mold at atmospheric pressure to cause the matrix binder to melt and infiltrate the encapsulated granules and abrasive particles.

摘要： A diamond impregnated drill bit features layered encapsulation of the diamond grit where the innermost layer is hardest or most abrasion resistant while succeeding layers are generally softer and less wear resistant. This can be accomplished by manipulating several variables in the encapsulation layers such as particle size or hard particle concentration. The outer layers can have added binder to make them softer. The encapsulated grit can be sintered or pre-sintered to make it less friable when handled. As a result the encapsulated diamonds are retained in the matrix longer with higher protrusion to improve bit longevity and penetration rates.
摘要翻译：金刚石浸渍钻头具有金刚石砂粒的分层封装，其中最内层是最硬的或最耐磨的，而后续的层通常更软和更少的耐磨性。这可以通过操作诸如粒度或硬粒子浓度的封装层中的若干变量来实现。外层可以添加粘合剂使其更柔软。包封的砂砾可以烧结或预烧结，使其在处理时变得更不易碎。因此，具有更高突出性的封装的钻石更长时间地保留在基体中，以提高钻头寿命和渗透速率。

摘要： An apparatus and method for determining a condition of a cutter coupled to a drill bit is disclosed. A support is configured to dispose the drill bit and the cutter at a selected location. A positioning device positions an ultrasonic transducer relative to the drill bit. The ultrasonic transducer and generates an ultrasonic pulse. A reflection of the ultrasonic pulse at a reflective surface of the cutter is obtained at the ultrasonic transducer. A processor receives the reflected pulse and forms an image of the reflective surface of the cutter using the reflected ultrasonic pulse while the cutter is coupled to the drill bit.

摘要： Control of the carbide volume in the matrix in an impregnated bit is accomplished by coating the hard particles in the matrix to space them further apart to increase the soft binder percentage in a controllable manner. The softer binder due to lower volume content of hard particles allows more rapid matrix wear in the softer formations to allow more diamond grit to cut better before getting flat spots and to be replaced faster with additional diamond grit further into the matrix as the higher content of the softer binder and the softer coating on the hard particles in the matrix promotes more effective cutting with more frequent emergence of diamond grit on the bit face as cutting progresses.
摘要翻译：通过将基质中的硬质颗粒涂覆在基质中来控制基体中的碳化物体积，使它们进一步分开，以可控的方式增加软粘合剂的百分比。由于较硬的颗粒体积含量，较软的粘合剂使得较软地层中的基体更容易磨损，从而允许更多的金刚石砂粒在得到平坦点之前更好地切割，并且在进一步加入到基质中的另外的金刚石砂粒中被更快地更换，因为更高的含量在切割过程中，较软的粘结剂和基体上的硬质颗粒上较软的涂层促进了更有效的切割，更频繁地在钻头上出现金刚石砂粒。
