Research status of joining technology of ceramic to metal

Joining components of ceramics and metal can make up for the deficiency in their individual performance,which change the situation of difficult forming and poor resistance to shock load of mono-complex ceramic parts in use,and the joining methods also reduce the manufacturing cost of composite materials. The corresponding joining methods include the most widely used brazing,self-propagating high-temperature synthesis（ SHS） joining,and solid-phase diffusion joining,and so on. Five kinds of common ceramics being taken as examples in this paper,the difficulties in joining ceramics to metal were analyzed,the current joining status of dissimilar materials between ceramics and metal were discussed. Besides,and the joining mechanism,technical characteristic and research status were introduced. At last,the prospect on the future development trend was proposed.
