TiC和AlN材料制备中的重力行为研究(Ⅰ)

STUDIES OF GRAVITY BEHAVIORS IN THE COURSE OF PRODUCING AlN AND TiC MATERIALS(Ⅰ)

为了研究失重环境对液相烧结AlN复合材料的影响 ,在抛物线飞行飞机上 ,以碳钛燃烧反应形成的高温作为实验热源 ,进行了失重实验和AlN复合材料、TiC材料制备中重力行为研究 .利用抛物线飞行时产生的不同重力环境 ,研究了不同重力水平对碳钛燃烧反应的影响 .研究结果显示 ,重力水平的差异导致燃烧温度不同 。

The gravity behaviors in the combustion synthesis of Ti and carbon on the parabolic flight aircraft were investigated. The results showed that the combustion temperatures vary with different gravity levels. Moreover, the study of gravity effect on combustion reaction in different sample orientations was also investigated.
