采用1600°C/30 Mpa/1h热压工艺制备了力学性能较好的碳纳米管-TiB2-Ni复合材料，研究了碳纳米管含量对复合材料组织结构和力学性能的影响。多壁碳纳米管(MWNTs)的加入可以显著提高TiB2金属陶瓷基复合材料的力学性能。增韧机制主要包括碳纳米管拔出、裂纹偏转、桥联和碳纳米管断裂。
Carbon nanotubes (CNTs)―TiB 2 ―Ni composites with improved mechanical properties were fabricated by hot pressing at 1600°C/30 MPa/1 h. The effects ofCNTs content on the microstructural feature and mechanical properties were investigated. The incorporation of multiwall carbon nanotubes (MWNTs) could significantly improve the mechanical properties of the TiB 2 cermet matrix composites. The main toughening mechanisms include CNTs pulling-out, crack deflexion, bridging, and CNTs rupture.
