Reinforced porous ceramic joint connection method
The present invention discloses a reinforced porous ceramic joint connection method, belongs to ceramic and similar / dissimilar material connection field, particularly relates to a porous ceramic joint connection method, and aims to solve the porous ceramic joint connection low strength problem in the prior art. The connection method is as follows: 1, an aqueous solution of silver nitrate is prepared; 2, an impregnated dried porous ceramic is obtained by ultrasonic impregnation; 3, a porous vacuum-sintered ceramic piece is obtained by vacuum sintering; and 4, a connected porous ceramic sample piece is obtained by porous ceramic connection, and reinforced porous ceramic joint connection is achieved. The advantages are as follows: the wettability of a solder on the porous ceramic can be improved by metallization processing, the molten solder is impregnated into the porous ceramic in the connection process, interface thermo-match can be improved, the connection interface residual stress can be alleviated, and the connecting strength and reliability of a connecting member can be improved. The reinforced porous ceramic joint connection method is mainly used for porous ceramic connection.
