摘　　要：针对SiCp/Al-MMCs的焊接问题,分别对国内外SiCp/Al-MMCs熔化焊、钎焊、搅拌摩擦焊以及扩散焊的研究现状进行了论述和分析。结果表明,可采用多种焊接方法实现SiCp/Al-MMCs的连接,但如何在避免焊接过程中生成脆性金属间化合物Al4C3的同时获得高强度接头仍是需攻克的核心问题。针对目前各种焊接方法中存在的问题对SiCp/Al-MMCs焊接技术未来的发展进行了分析和展望。为了获得高质量连接,可开发采用复合连接新技术和新工艺。Aiming at the welding problems of SiCp/Al-MMCs, the research status of fusion welding, brazing, friction stir welding and diffusion welding of SiCp/Al-MMCs at home and abroad were discussed and analyzed. The results show that the joining of SiCp/Al-MMCs can be realized by various welding methods, but how to avoid the formation of brittle compound Al4C3 during welding while obtain high-strength joints is still a core issue to be overcome. The future development of SiCp/Al-MMCs welding technology was analyzed and forecasted for the problems existing in various welding methods. In order to obtain high-quality connection, new composite joining technology and new process can be adopted.
