| 摘 要： | 采用高能球磨及热压方法制备银-金刚石合金，研究了金刚石添加相对银基触头材料组织、性能的影响。结果表明，高能球磨法能使金刚石粒子均匀分布在银基体内部，真空热压后，银基体内部的金刚石粒子呈纳米态分布。热压块体的密度能达到理论密度的94％以上。金刚石粒子的含量不同导致合金密度和硬度的变化。 |
| 关 键 词： | 触头材料 银／金刚石 纳米复合 |

| Abstract: | Ag/diamond contacts alloys with a nanoscaled microstructure of diamond particles was fabricated by high-energy ball milling, hot-pressing and sintering. Morphology and performance of the alloys were studied. The results show that the nanoscaled diamond particle dispersed inside Ag grains homogeneously. The morphological and crystal structure of diamond has no change after the prepare process. The density of hot-pressed block is more than 94% of the theory density. Different contents of diamond can lead to a hardness variant of the Ag/diamond alloy. |
| Keywords: | electrical contact silver/ diamond nano-composite material |
