Research abstract
GRADED COMPOSITION/PROPERTY INSERT MATERIALS ARE PROPOSED FOR TWO STEP BRAZING OF BULK SILICON NITRIDE TO DUCTILE IRON, 4340 STEEL OR WARPALLOY. THE INSERT MATERIALS PROVIDE GRADED MECHANICAL AND THERMAL EXPANSION PROPERTIES BETWEEN THOSE OF SILICON NITRIDE AND THOSE OF THE METALLIC MATERIAL OF INTEREST. BRAZED JOINTS BETWEEN SILICON NITRIDE/SILICON NITRIDE AND METAL/METAL ARE REQUIRED TO EFFECT BULK CERAMIC/METAL COMPONENT JOINING. A NOVEL METHOD OF PRODUCING THE GRADED COMPOSITION/PROPERTY INSERT MATERIALS IS PROPOSED. INSERT MATERIALS AND PROTOTYPE CERAMIC/METAL JOINTS PREPARED USING EACH OFTEH THREE METALLIC MATERIALS OF INTEREST WILL BE EVALUATED ON THE BASIS OF METALLOGRAPHIC EXAMINATION AND MECHANICAL PROPERTY MEASUREMENTS.
