| Abstract: | Al2O3 particals can be homogeneously distributed in molten aluminum alloys by means of alkali fused-salt, which is a new method of preparing aluminum matrix composite reinforced with Al2O3 particals. The effects offused-salt types, compositions, adding technology and the size of Al2O3 particals on the distribution of the particals in in the matrix were studied. The room temperature mechanical property of the composite was tested. Results show that this composite has
the following advantages: particals well combined with matrix, mechanical properties improved,
hardness greatly increased. The material can be employed in the wear resistant parts in engines. |
