Abstract Scope |
This paper investigates the brazing of stainless-steel Composite Metal Foams (CMFs) using both copper and Nickel-based brazing alloy (BNi-2) as filler materials, performed under vacuum environment. Our main goal is to compare the performance of the CMF material when joined using these two different brazing methods. The aim is to preserve the foam's porous structure and minimize any degradation of its mechanical properties that can occur during high-temperature bonding processes. In comparison to other joining techniques like induction welding and diffusion bonding, as documented in prior reports, brazing proved to be a highly efficient method. This efficiency stems from the use of fillers, which results in minimal disruption to the foam's inherent porosities. This work details the brazing setup, the characterization of the resulting brazed samples, and the structural integrity of the hollow spheres within the CMF. The findings of this study suggest that brazing is a dependable and effective joining technique for incorporating CMFs into demanding, load-bearing applications. |
