| 摘 要： | 采用稀土La掺杂的添加方式，优选富铁硬质合金基体的配方，通过基体的力学性质测试以及金相分析确定了YGl5富铁硬质合金的基体配方，确定出最佳稀土La添加量为0．5％质量比。单齿抗冲击试验表明，这种复合齿具有良好的抗冲击性能。室内钻进试验说明，适当配方的稀土富铁金刚石增强型硬质合金复合齿具有良好的抗冲击性，较强的研磨能力和对岩样的广谱性。同时，通过野外实际钻进进一步说明，这种复合齿钻头具有高时效性。通过调整金刚石的镀覆方式和物质，金刚石浓度以及烧结工艺，来控制复合齿的性能，从而使稀土富铁金刚石增强型硬质合金复合齿钻头具有高时效、长寿命等特点。

| Abstract: | This paper adapts adulterated mode of adding rare earth lanthanum, and selects matrix formula of rare earth & abundant ferrum carbide tungsten, then matrix mechanics capability and metallic phase analysis confirm a kind of optimum matrix formula of rare earth & abundant ferrum. Adulterating different amount of lanthanum in rare earth & high ferrum matrix, by mechanics capability and metallic phase analysis, this paper confirms the optimum amount of adulterating lanthanum is 0.5 percent of weight. Indoor single button impact testing shows composite buttons have excellent impact strength. Aiming at different special stratum, this paper chooses several representative rocks and concretes to drill indoor, and indoor drilling of rare earth & abundant ferrum diamond enhanced carbide tungsten composite button bit shows that composite buttons of suitable formulas have good impact strength & abrasion ability. Field drilling shows its bit has high penetration rate. By choosing different coating methods, materials, concentration of diamond, and sintering techniques, we can adjust performance of diamond enhanced composite button, then make rare earth & abundant ferrum diamond enhanced composite button bit have high drilling rate and long life-span characteristics. |
