Abstract: Advanced ceramics are becoming the new type engineering materials because of their excellent performances.It is often required to join them to metals in the engineering application.However,it is difficult to get satisfactorily joint due to the great difference in the microstructure and physicalchemical characteristics between ceramic and metal.The problem may be solved by using the gradient transitional layer,within which the composition and microstructure can vary gradiently,as a weld interlayer between ceramic and metal.In this paper,the Self-propagating High-temperature Synthesis(SHS) technique is introduced to the welding between ceramic and metal and the synthesis process of the gradient transitional layer of ceramic metal is investigated.The results shown that the gradient transitional layer of ceramic/metal can be fabricated successfully by means of SHS technique and the thermal stress at the interface of ceramics and metal caused by the difference in expansion coefficient between them can be effectively moderated during welding.This method may set up a new way for welding dissimilar materials to obtain a weld with better performances.
