摘要
本文对比了分段升压,慢超压和分段慢超压三种升温升压方式在合成立方氮化硼时的合成效果。通过实验和分析确定,在合成立方氮化硼时分段慢超压是一种好的升温升压方式。指出减慢超压速度有利于减少合成腔内的压力梯度,得到好的合成效果。
In this paper,the experiment results of cBN synthesis are analysed when using stepped elevating pressure,slow elevating pressure,and stepped and slow elevating pressure methods in the process of cBN synthesis.The results shows that the stepped and slow elevating pressure is the best technique for the cBN synthesis,and put forward that slow elevating pressure can modify the pressure gradient in the synthesiz /ing sample and improve the results of cBN synthesis.
