ZrB_2-SiC eutectic powders with a lamellar texture was prepared, and then the powders were sintered without sintering additive by spark plasma sintering. Dense ZrB_2-SiC eutectic composites with the lamellar texture were successfully fabricated. The ZrB_2-SiC eutectic composites had similar mechanical properties and oxidation resistance to typical ZrB_2-SiC composites.

制备了Zrb_2-Sic-sic Eutectic粉末，并制备了层状质地，然后将粉末烧结而不会因Spark等离子体烧结而烧结。具有层状纹理的密集Zrb_2-SIC共晶复合材料已成功制造。 ZRB_2-SIC共晶复合材料具有相似的机械性能和与典型ZRB_2-SIC复合材料的氧化抗性。
