本研究采用超声辅助浸渍技术，在熔融锡基焊料中浸渍氧化锆陶瓷，实现了氧化锆陶瓷的低温连接。采用扫描电子显微镜和能谱仪、X射线衍射仪和X射线光电子能谱研究了超声振动对锡/氧化锆界面组织结构的影响，探讨了锡涂层与氧化锆陶瓷的连接机理。结果表明，在S熔体中超声浸锡1200h后，在ZrO2表面形成了厚度约为8~9µm的纯锡焊料层。锡涂层与氧化锆陶瓷具有良好的冶金结合性能。在界面处形成了纳米级的ZrSnO4三元相，有利于晶格从锡焊料向氧化锆陶瓷的顺利过渡。由于声空化作用引起了锡、氧和氧化锆在熔融的锡/氧化锆陶瓷界面上的高温反应，从而形成了氧化锌中间层。试验结果表明，ZrO2/Sn2/ZrO2焊点的平均剪切强度约为32 Mpa，剪切破坏主要发生在焊料层内。
Ultrasound-assisted dipping of ZrO2ceramics into molten Sn solder was performed to realize the low-temperature joining of ZrO2ceramics in this study. Scanning electron microscopy with energy dispersive spectrometer, X-ray diffraction and X-ray photoelectron spectroscopy were employed to study the effects of ultrasonic vibration on the microstructure of Sn/ZrO2interface, and to elucidate the joining mechanism between Sn coating layer and ZrO2ceramic. Results showed that, after ultrasonically dipping in molten Sn for 1200 s, a pure Sn solder layer with a thickness of approximately 8–9 µm was coated on the ZrO2surface. The Sn coating layer exhibited excellent metallurgic bonding with ZrO2ceramic. A nano-sized ZrSnO4ternary phase, which was beneficial to the smooth transition of the lattice from Sn solder to ZrO2ceramic, was formed at the Sn/ZrO2interface. The formation of ZrSnO4interlayer was ascribed to the acoustic cavitation induced high-temperature reaction of Sn, O and ZrO2at the molten Sn/ZrO2ceramic interface. The tested average shear strength of ZrO2/Sn/ZrO2joints was approximately 32 MPa, and the shearing failure mainly took place within the Sn solder layer.
