摘要
本文研究了铝—石墨复合材料的制备.结果表明,铝合金中添加一定量的元素钛后,可以通过向铝液中直接加入不经镀覆的颗粒石墨而制得铝—石墨复合材料.并且铝合金的含钛量和石墨粒度对于铝—石墨复合材料中的最大石墨含量有很大的影响.文中分析了这种影响的原因.
The production of Aluminium-Graphite composite has been studied. It is shown the Al-Gr composite can be made by adding uncoated graphite partides into the molten aluminium alloy directly, if the aluminium alloy contains some titanium elemen . The content of Ti element and the size of graphite partides have a great influence on the maximum content of graphite in Al-Gr composite. And this phenomenon is explained.
