混合金属基复合材料是重要的工程材料,因为他们比纯铝具有更低的密度、更高的比强度和更好的物理力学性能而广泛应用于汽车、航空航天等方面。研究了混合铝金属基复合材料的力学性能和磨损性能。通过搅拌铸造将云母和SiC颗粒加入到Al 356合金中。采用扫描电子显微镜(SEM)研究样品的显微组织,用能谱分析(EDX)其化学成分。结果表明,所制备的Al/10SiC 3云母复合材料具有较好的强度和硬度。增加复合材料中云母含量能提高复合材料的耐磨性。 Mixed metal matrix composites are important engineering materials, because they have a lower density, higher specific strength and better physical and mechanical properties than pure aluminum and are widely used in automotive, aerospace and other fields. The mechanical properties and wear properties of the hybrid aluminum matrix composites were studied. Mica and SiC particles were added to the Al 356 alloy by stirring casting. The microstructure of the sample was examined by scanning electron microscopy (SEM) and the chemical composition was analyzed by energy dispersive spectroscopy (EDX). The results show that the prepared Al / 10SiC 3 mica composite material has good strength and hardness. Increasing the mica content in the composites can improve the wear resistance of the composites.
