An induction brazing method for joining Al 2 O 3 ceramic to 316L stainless steel (SS) was developed in this study. The Sn–Ti alloy was rapidly melted by induction heating, which enabled the active element Ti to react with O in Al 2 O 3. Consequently, a metallurgical bonding formed between and Al 2 O 3 and 316L SS. The microstructure of the joint was mainly composed of Fe 2 SnTi layer, FeSn 2 , Ti 6 Sn 5 particles and TiO layer. The maximum shear strength of 20 MPa was obtained at 260 A/140 s. The induction heating exhibited a higher heating rate compared to traditional resistance heating, as evidenced by the brazing process with only approximately 140 s. The proof-of-concept study on the induction brazing of Al 2 O 3 ceramic to 316L SS with high efficiency provides insights in the further development of ceramic/metal joining. [ABSTRACT FROM AUTHOR]
