金刚石钻头的寿命是评价钻头质量重要参数之一，而金刚石在胎体上的固结的牢度又是影响钻头寿命重要因素。目前通过人工合成金刚石的工艺水平的提高已有可能制造出接近于天然金刚石质量的单晶，因而进一步研究金刚石在胎体中的固结方式是提高钻头质量的重要途径。从目前制造孕镶金刚石钻头的方法来看基本上是两大类，一种是超室温条件下的烧结，另一种是室温条件下的利用电化学方法。超室温条件下的金刚石孕镶钻头制造工艺目前最普遍的方法是热压法，这种方法的特点是粘结金属在
The life of diamond bit is one of the important parameters to evaluate the quality of the bit, and the solidity of diamond on the carcass is another important factor affecting the life of the bit. At present, it has been possible to fabricate a single crystal close to the natural diamond by improving the technological level of the synthetic diamond. Therefore, further study on how to consolidate the diamond in the carcass is an important way to improve the quality of the bit. From the current method of manufacturing impregnated diamond drill point of view is basically two broad categories, one is super-room temperature sintering, the other is the use of electrochemical conditions at room temperature. The most common method currently used to make diamond inlay drills at room temperature is hot pressing. This method is characterized by a
