Abstract Scope |
Air brazing is a method for joining ceramics and metals used in high temperature applications such as gas separation devices and solid oxide fuel cells (SOFCs). We have previously conducted a series of high-temperature studies on the Ag-CuO system to understand its viability in creating long-lasting, oxidation resistant ceramic-ceramic and ceramic-metal joints. These studies include: an investigation of phase equilibria in the Ag–CuO system using a combination of thermal, microstructural and compositional analyses, high-temperature wetting and mechanical strength between select Ag-CuO compositions and various substrates. Our current collaboration with Aegis Technology has focused on developing an air braze tape product. In this presentation we will compare and contrast the strength of joints made with the tape product to prior results. |
