Design and Analysis of Ternary Coupling Bionic Bits

摘要：

In order to improve the penetration rate and the life of impregnated diamond bits, bionic coupling concept was introduced to the design of impregnated diamond bits. Ternary coupling bionic bits (briefly named bionic bits) were renascent non-smooth framework (three dimensional) manufactured by coupling physical and chemical methods from non-smooth shape and material. Experimental results show that bionic bits have higher penetration rate and longer life only when matrix material, matrix hardness and non-smooth ratio of the bits adapt to the strata to be drilled. Compared with the conventional impregnated diamond bits, the drilling rate and the life of bionic bits were increased by 43％ and 74％, respectively.
