摘　　要：论述了特种车辆动力系统隔热具有的重要意义和应用价值,热障陶瓷涂层的研究状况 以及隔热发动机研制的困难,指出了制约发动机低散热技术发展的主要因素。应用自蔓延高 温合成金属陶瓷涂层技术,探索了发动机复合隔热活塞的研制方法,分析了涂层结构的成分和 组织形态,通过热震性试验表明:在特种车辆动力系统应用自蔓延技术实现隔热是可行的。This article discusses the important military significance and the applied value by using heat insulation technology in special military vehicle driving system, introduces the development of heat barrier coat and the difficulties of heat insulation engine, points out the main factors which restrict the development of low heat rejection in engine. The coat cermet of piston is explored and made by using the Self-Propagating High temperature Synthesis（SHS） technology. The composition and microstructure of the ceramic coating are analyzed. It is feasible that SHS technology is used in the heat insulation of armored vehicle driving system according to the hot concussion examination.
