“…It can be found from previous studies that many scholars have studied the connection mechanism between ceramics and metals and obtained excellent composite materials [9][10][11]. However, the ceramics have good stability, thus some conventional solders are difficult to effectively wet the ceramic surface, so the connection between ceramic and SS cannot be realised [12,13]. In recent years, in addition to vacuum brazing [14], reactive air brazing [15] and diffusion bonding [16], there are also many new bonding methods, such as self-propagating high-temperature synthesis [17] and partial instantaneous liquid phase welding [18].…”

In this paper, the joining of ZrO2 ceramic and 304 stainless steel (SS) was realised by laser offset welding with AgCuTi filler metal. The heat was transferred from the molten pool to the solder through the unmelted SS. AgCuTi would diffuse to form eutectic products with low melting point, forming metallurgical reaction zone. The unmelted SS was retained by laser migration to avoid the mixing of molten solder and molten pool, which reduced the content of brittle phase in the joint. In addition, the crack-free welded joint with a tensile strength of 71 MPa was obtained. The elemental diffusion model was used to simulate the interfacial microstructure changes, and the microstructure was reasonably predicted by changing the welding parameters.

“…The joining methods of ceramic and SS [11] include physical vapour deposition (PVD), brazing, and diffusion welding. The difficulty in realising effective joining between ceramics and SS [12] mainly includes their major differences in physical and chemical properties. The great difference of linear expansion coefficient between ceramics and SS leads to large residual stress after welding and seriously reduces the mechanical properties of the ceramics/SS joint.…”

In this work, SS/ceramic composite material was produced by laser welding with active filler (AgCuTi). The presence of the AgCuTi filler was determined by ensuring that crack-free welds were obtained, and no brittle intermetallic compounds (IMCs) were observed. Unmelted SS was retained by laser offset to the SS side to achieve heat transfer to the filler. The AgCuTi filler was not melted but the eutectic reaction with low melting point still occurred by atomic diffusion. In accordance with the characteristics of laser brazing, a mathematical model for calculating the transient heat transfer of laser brazing was established via finite element method. The simulation results showed that the interface temperature could be directly controlled by controlling the welding power.
