Review paper on joining of alumina to metal through brazing

Joining of ceramics is a viable alternative manufacturing route to these of processing and shaping of large ceramic components with often complex geometries.Further, joining can offer cost and reliability advantages.Similarly ceramic-to-metal joining is usually essential for the fabrication of components that have ceramic inserts in otherwise metallic structures.Alumina ceramic was brazed to different metals such as Ti, Ni, Nb, Fe Different reaction products were formed at the alumina-metal interfaces, including solid solutions and intermetallic compounds.The alumina-Nb joint exhibited the highest bond strength value among the different couples, because Nb produces the lowest residual stress among the alumina-metal joints.In this Article different articles Review to join ceramic materials (Alumina) with metals.
