| 摘 要： | 采用扫描电子显微镜(SEM)和扫描俄歇微探针(AES)分别对NiMnCo粉末触媒合成金刚石不同阶段的断口组织、合成不同粒度金刚石断口和金刚石的生长界面进行了分析，研究结果表明：NiMnCo粉末触媒具有较宽的适用范围，既可以合成粗颗粒、高强度金刚石，又可以合成细粒度磨料级金刚石；在其合成体系中，碳能够实现三维方向扩散，有利于金刚石的对称长大，提高晶体完整性。

| Abstract: | The fracture sample of the diamond by NiMnCo powder catalyst at different stage of the synthesis, the fracture of the diamond with different diamond grain sizes and the interface where the diamond is crystallized were analyzed through SEM and AES, respectively. The results indicate that the NiMnCo powder catalyst is of wide application range, not only being used to synthesize coarse size and high strength diamond, but also being used to synthesize fine size diamond for grind materials. In the synthesis system, the carbon can diffuse in three directions, which is helpful for diamond to be crystallized symmetrically and to increase the integration of the crystal. |
