摘要
研究开发了一种喷射成形金属基复合材料制备新技术———熔铸- 原位反应喷射成形技术。该技术的突出优点是: 解决了颗粒损失和颗粒在合金基体中分布不均匀的问题; 合金的熔炼、颗粒的生成以及喷射成形金属基复合材料的制备同步进行, 明显缩短了复合材料的制备工艺流程, 降低了材料的制备成本。利用该技术制备了3 % TiC/Al 复合材料。研究表明, TiC 颗粒在铝基体中分布均匀, 制备的3 % TiC/Al
A new technique for manufacturing metal matrix composites by melt in situ reaction spray forming processing was introduced. The outstanding advantage of the technique is that the melting of alloys, the formation of the reinforcing particulates and the preparation of metal matrix composites take place in one step, which indicates that this will be a simple and cost effective technique for the manufacture of metal matrix composites. A 3%TiC/Al composite with TiC particulates homogeneously distributed in the aluminum matrix was produced by this technique.
