中文摘要:
      采用高频感应线圈加热,以蒸发.冷凝法制备了纳米铝粉,用空气进行钝化处理,得到有钝化层保护的纳米铝粉。使用透射电镜、场发射扫描电镜、X射线衍射、差热分析DTA等测试手段,研究了表面钝化处理对纳米铝粉抗氧化性能的影响。结果表明:经过表面钝化处理的纳米铝粉粒径范围为15 - 60nm,纳米铝粉表面包覆了3- 5nm厚的氧化铝膜,形成明显的核/壳结构,具有较好的抗氧化性能,这对于纳米铝粉的存储、活性保护机理的探讨有一定的意义。
英文摘要:
      Aluminum nanopowders were synthesized by high frequency induction evaporation condensation method, and aluminum nanopowders was treated by passivation in air. The influence of surface passivation treatment on the oxidization resistance of aluminum nanopowders was investigated by means of several techniques, such as TEM, ESEM, X-ray diffraction, differential thermal analysis. The results show that aluminum nanopowders treated by passivation with size from 15nm t0 60nm are covered by oxide layers with size from 3nm to Snm, and shape the core structure. Aluminum nanopowders have good oxidization resistance. It is very important for studying the mechanism of storing and activity protection about Aluminum nanopowders.
