Abstract
The product layer sequence in the reaction of solid Ti with alumina an d in the reaction of Ti dissolved in liquid Ag with alumina are compar ed. The phase diagram and the diffusion path in the Ti-Al-O system are used to describe the interface formation during brazing of alumina wi th liquid Ag-4 wt.% Ti filler material. During brazing, first Ti-Al(O) intermetallics are formed. When the filler material is depleted from Ti, the formed Ti-Al(O) intermetallics decompose in oxygen saturated T i(O) and Al, which in turn diffuses through the Ti(O) and dissolves in the Ag.
