Paper Title:
Wear Characteristics of Impregnated Diamond Bit in Drilling Armor Ceramic
  Abstract

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.
