摘　　要：文章介绍了超细FeCoCu预合金粉末应用于金刚石钻头胎体中的试验研究。通过基础性试验测试表明:在663Cu含量为30%的前提下,在金刚石钻头胎体组成成分中添加FeCoCu预合金粉末,通过调节其与WC粉末的配比关系,能够有效地调节钻头胎体硬度,适应不同的地层。通过回归分析得到了胎体硬度与FeCoCu粉末加量的数学关系式,由此关系式可预测胎体硬度或计算FeCoCu粉末加量。经过野外实际钻进试验证明:添加了FeCoCu粉末的金刚石钻头胎体综合性能具有较大的提高,为后续钻头耐磨性研究提供了经验积累。This paper introduces the experimental study on the application of ultrafine FeCoCu pre alloy powder in the matrix of diamond bits. According to the experimental data, with 663Cu contents of 30%, adding FeCoCu prealloy powder to the composition of the diamond bit matrix and by adjusting the proportion of FeCoCu powder and WC powder, the hardness of the diamond bit matrix can be effectively adjusted to adapt to different strata. Through the regression analysis, the mathematical relationship between the matrix hardness and FeCoCu contents is obtained, by which, the matrix hardness can be predicted and FeCoCu dosage also can be calculated. The actual drilling tests in field show that the comprehensive performance of the diamond bits matrix with FeCoCu pre-alloy powder is significantly improved, this experimental study provides experiences for further research on wear resistance of diamond bits.
