采用超声辅助浸渍法在Al 2 O3陶瓷表面制备Sn涂层，并分别与泡沫Ni增强Sn和Sn-9 Zn复合钎料进行超声钎焊。研究了超声钎焊时间对接头组织和力学性能的影响。采用超声浸渍法制备了与Al 2 O3陶瓷结合良好的纯Sn金属化层。复合钎料钎焊4s的Al 2 O3接头，焊缝中出现了不规则的Ni骨架，钎料基体中出现了气孔。在Sn-9 Zn/Ni界面处未发现反应相，而在Sn/Ni界面处形成了较薄的Ni 3Sn 4金属间化合物（IMC）层。超声钎焊时间增加到12 s，镍骨架被压缩成条状。在Al_2O_3/Ni-Sn/Al_2O_3接头中，Ni骨架间的间隙被Ni_3Sn_4层填充，并存在反应空穴。而在Al_2O_3/Ni-Sn_9 Zn/Al_2O_3接头中，Ni骨架间隙主要由（Ni，Zn）_3Sn_4颗粒填充，（Ni，Zn）_3Sn_4颗粒弥散分布于其间。钎焊12 s的Al 2 O3/Ni-Sn 9 Zn/Al 2 O3接头剪切强度最高，为53.45 MPa，接头剪切破坏发生在钎料层与Al 2 O3陶瓷的界面处。
Ultrasound-assisted dipping was performed to fabricate a Sn coating layer on the Al2O3ceramic, then the as-coated Al2O3ceramics were ultrasonically soldered with Ni-foam reinforced Sn and Sn-9Zn composite solders, respectively. Effects of ultrasonic soldering time on the microstructure and mechanical properties of joints were investigated. A pure Sn metallization layer which exhibited excellent metallurgic bonding with Al2O3ceramic was fabricated by ultrasonic dipping for more than 40 s. For Al2O3joints soldered with composite solders for 4 s, Ni skeletons distributed irregularly in the soldering seam and some pores existed in the base solders. A thin Ni3Sn4intermetallic compound (IMC) layer was formed at the Sn/Ni interface while no reaction phase was found at the Sn-9Zn/Ni interface. Increasing the ultrasonic soldering time to 12 s the Ni skeletons were compressed into a strip type. In the Al2O3/Ni-Sn/Al2O3joint, the gaps among Ni skeletons were filled with Ni3Sn4layers with some reaction cavities trapped in them. However, in the Al2O3/Ni-Sn9Zn/Al2O3joint, the Ni skeletons gaps were mainly filled with (Ni,Zn)3Sn4bulks with some (Ni,Zn)3Sn4particles dispersed between them. The Al2O3/Ni-Sn9Zn/Al2O3joint soldered for 12 s exhibited the highest shear strength of 53.45 MPa with the joint shear failed at the interface of filler metal layer and Al2O3ceramic.
