Ceramic-Metal Joining A method for improving the reliability of a ceramic-metal joint by reducing the dynamic mismatch stresses and strains on the ceramic due to the mismatch in thermal expansions of the two materials. This is done by bonding with a metal layer the ceramic to metal to form a bonding interfacial region between the ceramic and metal; and radially grading the interface region the thermal conductivity, thermal expansion coefficient, or tensile strength of the metal layer. An article in the form of a laterally graded, metallic bonding disc for overcoming problems of dynamic mismatch stresses and strains is also disclosed and claimed.
