METHOD OF JOINING AT LEAST TWO SINTERED BODIES AND COMPOSITE STRUCTURE PRODUCED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of joining at least two sintered bodies to form a composite structure, and to provide the composite structure produced by the method. SOLUTION: The method of joining at least two sintered bodies to form the composite structure includes: providing a joint material between joining surfaces of first and second sintered bodies; applying pressure from 1 kP to less than 5 MPa to provide an assembly; heating the assembly to a conforming temperature sufficient to allow the joint material to conform to the joining surfaces; and further heating the assembly to a joining temperature below a minimum sintering temperature of the first and second sintered bodies. The ceramic particles constitute 40-75 vol.% of the joint material, and include at least one element of the first and/or second sintered bodies. The composite structure produced by this method is also provided. COPYRIGHT: (C)2007,JPO&INPIT
