摘要
作者对铸造铝硅合金-石墨复合材料的磨损特性进行了研究,比较了含石墨与不含石墨的铝硅合金的耐磨性,並用扫描电镜对它们的磨损机理进行了考察。结果表明,铸造铝硅合金-石墨复合材料是一种摩擦性能良好的减摩材料,其在油润滑条件下的耐磨性比基体合金的高,在干摩擦、低载荷时的耐磨性也比较好。
The wear characteristics of cast Al-Si alloy-graphite composites are studied. Wear resistance of the composite is compared with the base Al-Si alloy.Arid the wear mechanism of the materials is investigated by means of scanning electron microscope. It is shown that the composite is a good anti-friction material. Its wear resistance under lubricating conditions, and under dry friction but lower load is better than that of the base Al-Si alloy.
