A Study on Interfacial Reaction and Titanium Distribution in Brazing Sapphire to Inconel 600 Using Cu/Ni Porous Composite

Abstract:

In this study, a Cu/Ni porous composite was introduced when brazing sapphire to Inconel 600 using a special active filler metal of BAg-8 + 2Ti. The aim of the research is to investigate the Ti distributionin the Cu/Niporous composite and braze joint. The brazing was carried out in brazingtemperature of 830°C for 30 minutes by a vacuum environment (10-4 Pa). The interface of braze joint/sapphire and braze joint/Inconel 600 were observed by an electron microscope followed by elements analyzing using SEM-EDS. The observation and analysis shows that there is a black and thin reaction layer at braze joint/sapphire interface and a non-uniform of reaction layer was formed at braze joint/Inconel 600 interface. The formation of reaction layer is influenced by thermodynamic activity of Ti during brazing.
