| 摘 要： | 为提高金的硬度，改善其耐磨性，提出了金的纳米颗粒强化方法，初步探讨了钨纳米颗粒对金的强化效果。在金的高频感应熔炼过程中，采用3mm厚的铸金板包覆钨纳米粉的方法，用质量分数约为0．12％的钨纳米颗粒强化入金基体，使金锭的硬度提高了20．5％。通过对强化结果的分析，指出了进一步改善纳米颗粒在金基体中的分散是提高纳米复合强化的关键。

| Abstract: | A nanoparticulate-reinforcing method of gold was presented in order to improve its hardness and hence the wearing quality. And the nanoparticulate-reinforced gold with tungsten was also preliminary investigated. During the high-frequency induction smelting of casting gold plates of 3 mm in thick and with nanotungsten encapsulated in, the hardness number of gold is enhanced by 20.5% for the mass fraction of nanotungsten of 0.12%. Through the analyses of the reinforcing results, it is shown that the further improvement for the dispersion degree of nanotungsten in gold is a key factor, and it is worthy of further studying to improve the smelting ambience of gold and to select some other stable nanoparticulates. |
