Interfacial Reaction of Alumina Ceramics to Mild Steel Braze Joint
Al2O3 is brazed with mild steel using 70Ag-27Cu-3Ti (wt.%) active filler alloy at 900°C for 5 min. The interfacial reaction products are analyzed with X-ray diffraction (XRD)．The interfacial phases are analyzed with EDAX. According to the experimental observations, the interfaces developed during brazing have been systematically characterized and the structure are separately Ti3Cu3O/Ti3Al+ TiMn+TiFe2 +Ag(s,s)+Cu(s,s)/TiC from alumina ceramics side to mild steel side.
