Research abstract
A METHODOLOGY FOR JOINING RF OR IR DOME MATERIALS TO METALS BY LASER BRAZING WILL BE DEVELOPED AND DEMONSTRATED. THE APPROACH USED WILL AVOID THERMAL STRESS CRACKING OF THE CERAMIC DURING BRAZING BY MINIMIZING THE MASS OF MATERIAL THAT MUST BE HEATED TO BRAZING TEMPERATURE. BRAZING EXPERIMENT VARIABLES WILL INCLUDE SYSTEMATIC MODIFICATION OF THE METAL CONFIGURATION AS WELL AS THE LASER POWER AND HEATING TIME. FINITE ELEMENT THERMOSTRUCTURAL ANALYSIS TECHNIQUES WILL BE USED TO ASSIST IN SELECTION OF EXPERIMENTAL VARIABLES.
