摘　　要：研究了纳米碳管对PcBN烧结片的显微组织、硬度与冲击韧性的影响。结果表明：在高温高压烧结过程中,添加CNT后,PcBN的强度、韧性增加。当纳米碳管的含量为2wt%时,PcBN表现出优良的力学性能。The effects of carbon nanotubes on the microstructure, hardness and impact toughness of sintered PcBN sheet were investigated. The results show that the strength and the toughness of PcBN after adding CNT improve during sintering process under high temperature and high pressure. The mechanical property of PcBN is optimal, when the content of CNT is 2wt%.
