摘要: Abstract Zirconia (3Y-PSZ) and titanium were joined by active brazing in vacuum with the 63 Ag–35.25 Cu–1.75 Ti (wt.%) filler at 840–870 °C under different contact loads. Brazing conditions did not affect noticeably joint mechanical strength but a remarkable change of interlayer microstructure was found. This evolution affected fracture behavior: ductile through Ag-rich area changed to brittle one intermetallic titanium–filler interface after long soaking maximum temperature.
