摘　　要：为了解决热机碎岩钻头摩擦元件耐高温、耐摩擦等性能不足问题,对摩擦元件材料进行研究,包括胎体材料选择、配方设计等。试验结果表明,用陶瓷代替硬质合金作为热机碎岩钻头的摩擦材料是可行的,利用热压烧结工艺可以将陶瓷固定在钻头上。In order to overcome the shortages of the friction element of thermal-mechanical bit in wear resistance and heat resistance, researches were made on the element material, including choice and design of matrix material. The results show that it is feasible to use ceramics as friction element material instead of hard alloy, or to fix the ceramics on the bit by hot press sintering process.
