Аннотация: Nano-NbC and nano-WC were added to the WC-bronze based matrix to improve the performance of the matrix of the impregnated diamond bit. The uniform design method, regression analysis and solver were used to obtain the optimal addition. Laboratory drilling experiments of the strengthened bits were carried out. The results show that after adding nanoparticles, the hardness and the bending strength of the matrix are improved by up to 25.23% and 5.73%. The wear resistance of the diamond composites is significantly increased, with wear ratio increased by up to 57.4%, indicating that the diamond and the matrix are more closely bonded. In conclusion, adding nanoparticles has positive significance on the performance of diamond composites. The mechanical drilling speed of the strengthened bits is 19.63% higher than that of the blank diamond bit, and that the matrix wear is reduced by 32.84%, indicating that the addition of nanoparticles to the matrix can strengthen the drill bit and improve drilling efficiency. © 2022 Zhengzhou Institute of Abrasives Grinding.
