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更快地被更换，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。

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.
