摘要以ZrC和 ZrB₂粉末为原料,采用放电等离子烧结法在1 750 ℃和1 850 ℃烧结制备ZrB₂含量(质量分数)分别为5%,10%,15%的ZrC-ZrB₂复合陶瓷材料,研究ZrB₂含量对材料组织与性能的影响。结果表明： ZrC-ZrB₂复合材料表面形貌呈鳞片状, 随ZrB₂含量增加,晶粒变细。当烧结温度为1 750 ℃时,随ZrB₂含量增加,材料密度降低,但断裂韧性提高,ZrB₂含量为15%时断裂韧性达到11.972 MPa·m^1/2,而ZrB₂含量为10%时,材料硬度最大,为16.868 GPa。与1750℃烧结的ZrC-ZrB₂复合材料相比,烧结温度为1 850 ℃时材料发生再结晶与晶粒长大,整体力学性能下降,随ZrB₂含量增加,材料密度降低,但仍有晶粒细化与力学性能升高的趋势。

Abstract：Using ZrC and ZrB₂ powders as raw materials, ZrC-ZrB₂ composite ceramic bulk materials with ZrB₂ content (mass fraction) of 5%, 10%, and 15% were prepared at 1 750 ℃ and 1 850 ℃ respectively by spark plasma sintering. The effects of ZrB₂ content on the microstructure and properties of the composites were studied. The results show that the surface morphology of ZrC-ZrB₂ composite is scaly, with the increase of ZrB₂ content, the grain becomes finer. When the sintering temperature is 1 750 ℃, with the increase of ZrB₂ content, the material density decreases, but the fracture toughness increases. When the content of ZrB₂ is 15%, the fracture toughness reaches 11.972 MPa·m^1/2, while when the content of ZrB₂ is 10%, the hardness is the highest of 16.868 GPa. Compared with the ZrC-ZrB₂ composites sintered at 1 750 ℃, when the sintering temperature is 1 850 ℃, recrystallization and grain growth occur, and the overall mechanical properties decrease. With the increase of ZrB₂ content, the density of the composites decreases, but the size of grain decreases and mechanical properties increases.

Key words： zirconium carbide zirconium boride spark plasma sintering microstructure Vickers hardness fracture toughness
