The sintering parameters of hot-pressing diamond drill bit mainly contains the sintering temperature, holding time, sintering pressure and the pressurized method. The length of holding time is directly related to the performance of diamond drill bit. This article mainly discusses the effect of holding time on the performance of diamond drill bit. First, a general formula of diamond drill bit is chosen. A group of samples in this parameter were loaded and sintered. Holding time is set as variable, while other parameters remain the same. The optimal holding time for this formula is obtained through the mechanical properties tests on the samples’ bending, tension, compression, and hardness, and fracture analysis using scanning electron microscopy (SEM).

High pressure is demanded in producting diamond bit by cold-pressing. Although the pressure could be reduced by hot-pressing, a certain pressure is demanded to ensure the compactness of diamond bit matrix. Four sintering parameters, sintering temperature, holding time, sintering pressure and the pressing mode, are mainly included during producting diamond bit by hot-pressing. This article mainly discusses the effect of sintering pressure on the properties of diamond bit. First, select a general formula of diamond bit, take sintering pressure as variable, other parameters remaining immovability; then load and sinter a set of samples in this parameter. Testing and analysing the samples by mechanical properties test, such as bending, tension, compression, and rigidity, and SEM fracture analysis, we obtain the optimum sintering pressure in this formula.

“…The extreme hardness and rigidity, as well as the excellent thermal conductivity (>1500 W/mK), low thermal expansion (2,3 × 10 − 6 K − 1 ), and good abrasion resistance of the micro/nanodiamond particles [1,2] make them the perfect reinforcement to be used in the manufacture of abrasive tools, with improved wear resistance capable of cutting, grinding, sawing, drilling and polishing hard materials [3,4]; such as stone [5], optical glass [6], concrete [7], cemented carbides [8], engineering ceramics [9], etc. However, diamonds are extremely inert in contact with most metals, and therefore it is very difficult to create a strong bond between diamonds and metal surfaces due to their poor wettability and considerable differences in the coefficients of thermal expansion.…”
