Influence of Processing Parameters on the Strength of Air Brazed Alumina Joints Using Aluminium Interlayer

Effect of ultrasonic transmission rate on microstructure and properties of the ultrasonic-assisted brazing of Cu to alumina

“…Additionally, as aluminum has a good wettability for alumina ceramic, the fillers consisting of aluminum are frequently used to braze ceramics [13]. Furthermore, acoustic cavitation effects have been verified, which are generated by high-intensity power ultrasonic waves during their propagating through molten filler metals [14,15], which can break the oxides and promote wetting of molten filler metals on brazing material surfaces [16,17].…”

Effect of Joining Conditions on the Shear Strength of Barium Titanate Joint Brazed with Molten Aluminum

“…For cast-in insertion processes, the main factors in uencing the resulting joint strength of ceramics with metal include the wettability, surface roughness 9) , temperature, pressure, holding time and atmosphere [10][11][12][13][14] . These factors may affect interdiffusion, interfacial reactions and oxidation behavior, as well as the interfacial contact 3,[9][10][11][12][13][14] .…”

“…These factors may affect interdiffusion, interfacial reactions and oxidation behavior, as well as the interfacial contact 3,[9][10][11][12][13][14] . In some cases, relatively higher joint strengths can be obtained under atmospheric conditions 13) , which is a useful feature in industrial settings. However, the particular factors in uencing the joint strength obtained by cast-in insertion of aluminum with BaTiO 3 have not been determined.…”

Microstructure and mechanical properties of diffusion-bonded Mg–Al joints using silver film as interlayer

“…Some initial work has already been done, such as diffusion bonding of Mg and Al using Zn-based alloy interlayers, laser-TIG hybrid welding of dissimilar Mg and Al alloys with Ce interlayers, and laser-welded Mg and Al alloys using Ti interlayers [13][14][15]. The diffusion bonding process parameters including bonding temperature, holding time and pressure are key factors in interfacial structures, compound formation and bonding strength of the joints [16][17][18][19][20]. The selection of proper process parameters can greatly improve the quality of the joints, especially for bonding Mg and Al [21,22].…”
