ZrO2 ceramics were brazed with Ni-Ti filler metal. The microstructure of the joint and the effect of holding time on the interfacial microstructure and mechanical property were investigated. The results show that TiO+Ni2Ti4O layer is formed at the interface of ceramic and filler metal at 1 350 ℃ for 10 min. TiO distributes as a discontinuous layer next to the ceramic, while Ni2Ti4O is a continuous layer. The center of brazing seam consists of NiTi and Ni3Ti. TiO decreases and finally disappears, the thickness of Ni2Ti4O layer increases with the increase of holding time. Some cracks appear in Ni2Ti4O layer when the holding time is 40 min. The shear strength of the joints firstly increases and then decreases with increasing holding time. The shear strength of the joint reaches the maximum value of 88.7 MPa when the holding time is 30 min.
