摘　　要：在分析盘式钻头齿圈失效机理的基础上,提出了齿圈表面堆焊耐磨合金强化和镶嵌硬质合金齿圈强化两种方法。通过试验研究和对比分析,确定了采用冶金混合烧结固齿法镶嵌硬质合金齿圈强化盘式钻头。进一步的试验研究表明:采用冶金混合烧结固齿法镶嵌硬质合金齿圈来强化盘式钻头齿圈,其结合情况非常好;硬质合金齿圈的硬度、耐磨料磨损的能力和耐冲击磨料磨损的能力在烧结后都有进一步的提高,说明采用冶金混合烧结固齿法镶嵌硬质合金齿圈来强化盘式钻头齿圈是可行的。Based on an analysis of failure mechanism of tooth row of a disk bit, two kinds of preventive measures are put forward, i.e. anti-wear alloy welding on the surface of the tooth row and hard alloy inserting, and the latter is determined to use in the strengthening of the tooth row of the disk bit by means of experimental study. The hard alloy is inserted in the tooth row with the metallurgical sintering method. The result of the experiment shows that the hardness and wear resistance of the hard-alloy tooth row are improved after sintering, and the tooth row combines very well with the bit.
