AbstractBrazing of ceramic and metal components is an emerging manufacturing technology in which a furnace or a heat source is used to join the substrates using a brazing filler material. Brazing of ceramic and metal has received considerable attention in the field of nuclear reactor, aerospace, automobile, medical and electrical engineering. A brazing alloy can either be a conventional brazing alloy which requires the ceramic surface to be metalized or an active brazing alloy which does not require metallization. A sound interfacial adhesive bond is formed during the process. Vacuum brazing of alumina and steel (SS304) with Cusil active brazing alloy has been carried out for the analysis of behavior of joint in different loading condition. Uniformity and presence of defects of the joints is confirmed by observing the Scanning electron microscope (SEM) images. The elements and phases present in the joint interface are observed by energy dispersive spectroscopy (EDX) and X-ray diffraction (XRD) analyses. Average shear stress was found to be 88 ±8MPa. The micro- Vickers hardness test showed that the micro hardness of the interface was lower than the substrates.
