【摘要】 高温高压下利用镍钛液相合金浸渍扩散进行的人造金刚石多晶烧结过程中,金刚石晶粒表面经历了石墨化过程。本文对此石墨化现象进行了表面分析,发现在金刚石晶粒表面石墨化过程中,伴随着无定形碳的形成。更多还原

【Abstract】 The surfaces of diamond grains will undergo a process of graphi-tization when diamond powders are sintered with the aid of the infusion anddiffusion of Ni-Ti alloy binder at high temperatures and high pressures. Thephenomenon of graphitization has been studied by the method of surface analysis.It has been found that amorphous carbon is produced along with thegraphitization process of diamonds.更多还原
