    摘要:

    采用高能球磨及熱壓方法制備銀-金剛石合金，研究了金剛石添加相對銀基觸頭材料組織、性能的影響。結果表明，高能球磨法能使金剛石粒子均勻分布在銀基體內部，真空熱壓后，銀基體內部的金剛石粒子呈納米態(tài)分布。熱壓塊體的密度能達到理論密度的94％以上。金剛石粒子的含量不同導致合金密度和硬度的變化。

    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.
