| 摘 要： | 采用化学镀技术，在高能球磨所得纳米石墨粉上包覆银，制得纳米晶银／石墨包覆粉体，经冷压、烧结、复压工序，制备了AgC5触头材料。采用此新工艺制备的触头材料与常规工艺制得的相比，在力学和物理性能等方面有了较大的提高。分断实验表明：将纳米技术应用到银／石墨触头材料的制备中，使材料的抗电弧磨损性能有了较大的改善。 |
| 关 键 词： | 化学包覆 高能球磨 纳米石墨 银／石墨触头材料 电弧磨损 |

| Abstract: | Using electroless plating, the nanocrystalline graphite powder coated with silver was prepared from nano-graphite obtained by high-energy ball milling. By pressing, sintering and re-pressing, the AgC 5 electrical contact material was fabricated. The electrical contact material prepared by the novel process has great improvement in mechanical, physical properties. The make-break test shows that AgC 5 contact material fabricated by nano-phase coating possesses good resistance against arc erosion. |
| Keywords: | chemical coating high-energy ball milling nano-graphite silver/graphite contact material resistance against arc erosion |
