Abstract:
1. A method of joining a metal to a ceramic material comprising: providing a metal and a ceramic material comprising a ceramic matrix composite selected from silicon carbide/silicon carbide (SiC/SiC), ceramic oxide, ceramic carbide, ceramic nitride, or combinations thereof, or a ceramic material selected from alumina, aluminum nitride, boron carbide/nitride, and silicon carbon/nitride; providing a compliant interlayer having a coefficient of thermal expansion which is between the coefficient of thermal expansion of the metal and the coefficient of thermal expansion of the ceramic material; welding said compliant interlayer directly to said metal to form a bonded interlayer/metal; and bonding said ceramic material to said bonded interlayer/metal with a brazing material.
