摘要
本文利用燃烧合成工艺制备了原位反应的 Al2 O3加少量 Cr的陶瓷基复合材料 ,并对其组织结构及形成机理进行了研究与分析。
This paper deals with the investigation of Al 2O 3 ceramic compounding little metal Cr ceramic matrix material formed by combustion synthesis reaction. And also the micro structure and growing mechanism are analyzed. The result shows that the hardness of Al 2O 3/Cr ceramic matrixcompound is much higher than sinter pure Al 2O 3 ceramic. The growth of Al 2O 3crystal is jumping with the formation of each cubic unit.
