摘要
碳化硅颗粒增强铝基复合材料,由于具有高的比强度、比模量、良好的热传导率、可调的热膨胀系数等优异性能,在航空航天、电子封装等领域得到了广泛应用。无压渗透是近年来发展起来的制备这种复合材料的较好方法。我们在综合分析其技术特点的基础上,在空气气氛下制备了不同 Si 含量的样品。从显微结构分析看,空气气氛下制备铝碳化硅复合材料是可行的,而且 Si 含量为12%时。渗透较好。
Due to the high specific intensity and module, good thermal conductivity and tailor thermal expansion coefficient, SiCp/Al composite has been applied to abroad fields, such as spaceflight and electronic packaging. Pressureless infiltration is an excellent method for the preparation of SiCp/Al composite recently. In the base of the preparation states on SiCp/Al composite in the air, the samples with different Si content were prepared. From the microstructure, it is feasible to fabricate SiCp/Al composite in the air. What＇ s more, infiltration is better when Si content is 12 % of the alloy.
