| 摘 要： | 将纳米ZrO2和SiC颗粒与微米WSi2／MoSi2颗粒进行球磨分散、混合，通过热压烧结制备ZrO2／SiC-WSi2／MoSi2复相陶瓷，研究了它的显微结构与耐磨性并与MoSi2材料进行了对比。结果表明：SiC、ZrO2纳米颗粒的复合化以及钨的合金化能使复相陶瓷晶粒细化，复相陶瓷的硬度较MoSiz陶瓷明显提高，耐磨性优于MoSiz陶瓷，磨损机制主要为粘着磨损兼有疲劳微断裂。

| Abstract: | ZrO2/SiC-WSi2/MoSi2 ceramic composites were prepared by hot-pressed sintering after ZrO2 and SiC nanoparticles were dispersed and mixed by wet-milling. The microstructure and wear resistance of the composites were investigated. The compositing of SiC and ZrO2 nanoparticles and alloying of W induced the grain of ceramic composites fined. The hardness and wear resistance of ceramic composites are much higher than those of MoSi2 ceramic. The wear mechanism is mainly adhesive wear accompanied with microfracture induced by fatigue. |

| Keywords: | ceramic composite microstructure wear resistance |
