To reduce the friction coefficient between impregnated diamond bit and rock, experiments on addition of graphite to the matrix material of bit cutters were conducted. The cutters were made up of diamond contained working layers and binding layers. The friction and wear properties of cutters and binding layers were investigated using a pin-on-disc friction & wear tester with granite as tribopair. The results showed that with addition of graphite, the hardness and friction coefficient of binding layer decreased, but its wear resistance increased; compared to cutters without graphite, those cutters containing graphite had lower wear loss and friction coefficient and their sliding wear process was much steadier, but diamond protrusion was still normal.

This paper describes the wear characteristics of impregnated diamond bits when drilling in Al2O3 armor ceramic. With different bits being developed, drilling experiments and scanning electron microscope (SEM) examinations were conducted, and the results show that diamond wear types consist of complete crystal shape, micro fragmentation, whole fragmentation, wearing flat and falling off of diamond; abrasive wear, impact abrasion and erosion exist in the wear of diamond and bond; diamond grain size and concentration have their optimal value under fixed machining conditions; diamonds of high quality could increase bit drilling efficiency and serving life; the bit whose abrasion rate of bond matches that of diamonds presents the best comprehensive properties.
