摘　　要：生产实践证明,在强研磨性或高硬度岩石钻进、切割过程中,在新型陶瓷材料机加工过程中,片状工艺生产的金刚石能够克服粉末工艺料出现的打滑或提前失效等问题,表现出突出的高锋利度、耐磨性和热稳定性。通过近三十年的金刚石合成及应用实践,结合晶体生长原理,结晶学基础理论以及与两面顶合成工艺的对比,文章概述了片状工艺金刚石合成工艺思路,并以此解释了它所表现出来的特性。During the process of drilling and cutting of strong abrasive rock or high hardness one,the production experience has proved that flake diamond can overcome the problems of skidding or premature failure of powder one in the machining process of new ceramic materials.It shows outstanding performance for high sharpness,wear resistance and thermal stability.Based on the diamond synthesis and practice application in the past 30 years,the principle of crystal growth and the basic theory of crystallography,and the comparison with the two-sided end synthesis process,this paper summarizes the idea of flake diamond synthesis process,and presents its characteristics accordingly.
