摘要
介绍了金属基陶瓷颗粒增强复合材料(metal matrix ceramic reinforced composites)的基体与陶瓷增强相的选择,同时指出如何有效地改善金属基体与陶瓷颗粒增强相之间的浸湿性问题。总结了烧结前期复合坯体的一些主要制备方法。又介绍了金属基陶瓷复合材料(MMC)的烧结工艺,重点介绍了通电烧结,比较了各新工艺的基本原理和优缺点,最后对金属基陶瓷颗粒增强复合材料进行了技术展望。
The selection of the metal matrixes and reinforcing particles for the composites and the ways to improve the wetability between them are reviewed. Main preparation methods for the composite blanks before sintering and sintering technologies are introduced with electric current sintering focused and different new technologies compared with each other. Finally, the future prospects of the composites are forecasted.
