项目摘要

Engineering ceramics are candidates for many structural, biological, and microelectronics applications. Direct fabrication of large, complex ceramic structures is difficult, and an approach that involves the assembly and joining of smaller components is often used. Joining is also often necessary when ceramic components are incorporated into metal-based structures to exploit their unique properties. The quality of the interfaces and joints produced during assembly impacts device performance. The difficulties associated with joining ceramics can limit or prevent their use. The proposed work will explore a novel approach to joining structural ceramics by means of foil interlayers based on high-melting-point metals. Joining ceramics to refractory metals has generally involved processes that require elevated temperature, long times, significant bonding pressure, and extremely careful preparation of the surfaces to be joined. Such characteristics make these combinations and these processes unattractive for mass production. The intellectual merit of the proposed work is focused on exploring the use of a multilayer interlayer combining a high-melting-point metal, Nb, and very thin coating layers of a lower-melting-point metal, Ni, to provide a joining process that can be implemented at reduced temperatures to rapidly produce robust, reliable refractory joints by means of a liquid-film-assisted, transient-liquid-phase bonding processing that does not require scrupulous surface preparation or high bonding pressures. The broader impact of such a manufacturing-friendly process includes the creation of many new opportunities to more easily and economically fabricate ceramic-based or ceramic-containing devices with new functionality. The basic science approach underlying the study will help facilitate the extension of the joining approach to other systems, while educating and training young researchers in this vital area.
工程陶瓷是许多结构、生物和微电子应用的候选材料。直接制造大型、复杂的陶瓷结构很困难,通常使用涉及组装和连接较小部件的方法。当将陶瓷部件合并到金属结构中以利用其独特性能时,连接通常也是必要的。组装过程中产生的接口和接头的质量会影响设备的性能。与连接陶瓷相关的困难可能会限制或阻止其使用。拟议的工作将探索一种通过基于高熔点金属的箔夹层连接结构陶瓷的新方法。将陶瓷连接到难熔金属通常涉及需要高温、长时间、显着的粘合压力以及对待连接表面进行极其仔细的准备的过程。这些特征使得这些组合和这些工艺对于大规模生产来说缺乏吸引力。所提出的工作的智力价值集中于探索使用多层中间层结合高熔点金属铌和非常薄的低熔点金属镍涂层,以提供一种可以在降低的温度下实施的连接工艺,通过液膜辅助的瞬态液相粘合工艺快速产生坚固、可靠的耐火接头 不需要严格的表面处理或高粘合压力。这种制造友好型工艺的更广泛影响包括创造许多新机会,更轻松、更经济地制造具有新功能的基于陶瓷或含陶瓷的设备。该研究背后的基础科学方法将有助于促进将连接方法扩展到其他系统,同时教育和培训这一重要领域的年轻研究人员。
