摘要

摘要: 为提高钻头胎体耐磨性与地层研磨性的适应性，提高钻头自锐能力，选取FeCoCu预合金粉作为胎体成分，对胎体性能进行研究。在碳化钨基胎体中添加FeCoCu预合金粉末，调节金刚石钻头胎体中FeCoCu粉末与WC粉末的配比关系，并在不同的烧结温度下烧制试样，寻找FeCoCu含量和烧结温度对胎体性能的影响规律。试验结果发现：随着FeCoCu含量的升高，胎体的相对致密度、洛氏硬度、抗弯强度和耐磨性随之降低；烧结温度对相对致密度、洛氏硬度、抗弯强度的影响幅度小，对胎体耐磨性的影响幅度大，最大变化幅度达到310%。FeCoCu预合金与烧结温度的耦合作用下，胎体的耐磨性变化存在较宽的调节区间，可通过二者组合的变化，调节胎体耐磨性，提高胎体对地层的适应性。

Abstract: FeCoCu pre-alloy powder was added into tungsten carbide matrix to find out the influence law of FeCoCu content and sintering temperature on matrix performance, aiming to improve the adaptability between bit matrix wear resistance and formation abradability and to enhance the self-sharpening ability of the bits. The ratio of FeCoCu to WC powder was adjusted and the matrix were sintered at different sintering temperatures. The test results show that with the increase of FeCoCu content, the performances of the matrix decrease, namely relative density, hardness, bending strength and wear resistance. It is also found that the sintering temperature has a significant impact on the wear resistance of the matrix, the maximum change of which reaches 310%; but it has small impact on other performances such as relative density, hardness and bending strength. In conclusion, the coupling effect of FeCoCu pre-alloy and sintering temperature provides a wide adjusting range for the wear resistance of the bits, whose adaptability to formations could be improved through the two-way adjustment of the two parameters.
