摘要：

Alumina ceramics were brazed to Inconel 600 and UMCo-50 superalloys at 900 C for 10 min using an Sn10Ag4Ti active filler metal. The brazing filler showed good wettability on alumina and super-alloys. The flexural strengths were 69 and 57 MPa for alumina/Inconel 600 and alumina/UMCo-50 joints, respectively. In both cases, the brazed specimens fractured along the Sn10Ag4Ti/superalloy interfaces after four-point bending tests. Electron probe microanalysis (EPMA) elemental mapping revealed that the Ni of Inconel 600 and the Co of UMCo-50 dissolved into Sn10Ag4Ti filler metal, which serves to reinforce the weak Sn10Ag4Ti matrix.
