项目摘要
The objective of this study is to identify, examine and understand new mechanisms by which ceramic constituents can be joined into complex multicomponent assemblies using multilayer metallic interlayers as bonding agents. The approach utilizes liquid-film- assisted joining (LFAJ), which exploits structural and chemical changes occurring over microscopic to macroscopic length scales to achieve bonding at temperatures low enough to minimize the microstructural and property degradation of temperature-sensitive components, thereby enabling the formation of material combinations inaccessible by conventional methods. The proposed work focuses on joining a model ceramic-metal combination, Al2O3-Nb, using Ni/Nb/Ni trilayers. During joining a thin liquid film of Nb-saturated Ni will allow rapid Nb transport, and should facilitate direct Al2O3-Nb bonding. Optimizing LFAJ will require microdesign of the trilayer structure and chemistry, and tailoring of the joining surfaces. This project will assess the feasibility of this approach, and contributes to an ability to understand and ultimately control the formation of strong and durable bonds between ceramic components, facilitating the development of assemblies with arbitrarily complex shape.The work will establish fundamental microstructure-processing- property relationships in a more complex model system than prior studies, providing a template to guide successful extension of LFAJ to other systems. It will expose new avenues for joining bulk ceramics to bulk metals, and train graduate and undergraduate students in the increasingly important science of joining that is vital to materials integration in a wide range of transportation, medical, electronic and energy industries. Publications and presentations at meetings will disseminate the results to the broader materials community.
本研究的目的是确定,检查和了解新的机制,陶瓷成分可以加入到复杂的多组分组件使用多层金属夹层作为粘合剂。该方法利用液膜辅助连接(LFAJ),其利用微观到宏观长度尺度上发生的结构和化学变化,以在足够低的温度下实现粘合,以最大限度地减少温度敏感部件的微观结构和性能退化,从而能够形成常规方法无法达到的材料组合。建议的工作重点是加入一个模型陶瓷-金属组合,Al 2 O3-Nb,使用Ni/Nb/Ni三层。在连接期间,Nb饱和的Ni的薄液体膜将允许快速Nb传输,并且应该促进直接Al 2 O3-Nb结合。优化LFAJ将需要三层结构和化学的微观设计,以及连接表面的剪裁。该项目将评估这种方法的可行性,并有助于理解和最终控制陶瓷部件之间形成坚固耐用的结合的能力,促进具有任意复杂形状的组件的开发。这项工作将在比以往研究更复杂的模型系统中建立基本的微观结构-加工-性能关系,提供了一个模板,以指导LFAJ成功地扩展到其他系统。它将揭示将大块陶瓷加入大块金属的新途径,并培养研究生和本科生在日益重要的科学中加入,这对运输,医疗,电子和能源行业的材料集成至关重要。出版物和在会议上的介绍将向更广泛的材料界传播结果。
