摘　　要：借助具有快速凝固特点的金属喷射成型思想,引入自蔓延高温合成技术,开发了一种制备新结构陶瓷材料的低成本、近终成型方法——自反应喷射成型陶瓷材料技术,并利用该技术制备了TiC-TiB2基结构陶瓷材料。通过理论分析与初步实验研究,论证了其可行性,并分析了材料的组织结构。A new technology, self-reactive spray forming, to prepare ceramic materials with low cost and nearly final molding properties is advanced by introducing the Self-propagating High-temperature Synthesis（SHS） technology to the metal spray forming technology. And TiC-TiB2-based structure ceramic is prepared by the new technology. By the theory analysis and fundamental experiment researches, the feasibility of the new technology is demonstrated. The structure of the self-reactive spray formed materials is analyzed.
