THE BRAZED JOINTS BETWEEN THE PURE AL2O3 AND TI (1- 2 % ALLOYING ELEMENTS) IN PRESENCE OF SILVER EUTECTIC BRAZING ALLOY BVAG-8

It is the metallographic study of brazed joint between the pure alumina with alloyed Titanium (up to 1-2 % of alloying elements) by using BVAg-8 as braze filler metal. Experiments were performed to study about the behaviour of filler at the interface, bonding strength of the two & metallographic study is performed. Temperature above 930ºC has the appreciable bonding strength but simultaneously it is expected to have lower corrosion current density. Variation in the brazing temperature and other parameters results to have a sound bonding. Metallographic study shows that braze filler have role in joining and the temperature above/around 930ºC. So that it can be used effectively at UHV application
