采用陶瓷注射成型（CIM）制备碳化硅预制体并对铝合金进行无压渗透，实现了高性能SiCp/Al复合材料的净成形。制备的SiCp/Al零件尺寸精度可达+/- 0.3%左右，性能也能较好地满足电子封装对材料的要求。本文详细讨论了SiC预制体的CIM工艺和SiC预制体在铝合金中的渗透。此外，还对制备的SiCp/Al复合材料的性能进行了研究和评价。(C) 2009 Elsevier B.V.版权所有
High performance SiCp/Al composites have been realized their net-shape forming by use of a novel process-ceramic injection molding (CIM) for the preparation of SiC preform and pressureless infiltration of aluminum alloys. The dimension precision of prepared SiCp/Al parts could reach about +/- 0.3%, and their properties could also better meet the requirement of electronic packaging on the materials. In this paper, the CIM process to fabricate SiC preform and the infiltration of SiC preform by Al alloys have been discussed in detail. Additionally, the properties of prepared SiCp/Al composites have also been given research and evaluation. (C) 2009 Elsevier B.V. All rights reserved.
