Porous ceramic connecting method
The invention relates to a porous ceramic connecting method, relates to a ceramic connecting method, and aims to solve the problem that the process is complex when wettability is improved and thermal stress is relieved simultaneously when conventional porous ceramic is connected with metals. The porous ceramic connecting method comprises the following steps: I, preparing an organic phenolic resin solution; II, performing thermal treatment on porous ceramic; and III, connecting the porous ceramic. Due to a surface layer pore structure of the porous structure, a brazing filler metal can permeate into a base body to form a connecting structure with mechanical occlusion and chemical bond combination, not only is residual thermal stress of a connector effectively relieved, but also a boundary reaction combination area is increased, and the strength of the connector can be improved. The porous ceramic connecting method is applied to the field of connection of ceramic and metal materials.
