WebThe usual filler metals and fluxes for brazing aluminum to aluminum can be used, or the Silver Alloy filler metals BAg-1 and BAg-1a can be used if heating and cooling are rapid (to minimize diffusion). Pre-tinning the copper surfaces with solder or silver alloy filler metal improves wetting and permits shorter time at brazing temperature. WebThe study focused on dissimilar brazing of metallized YSZ (Yttria-Stabilized Zirconia) and Crofer alloy using BAg-8 (72Ag-28Cu, wt%) filler foil. The YSZ substrate was metallized by sequentially sputtering Ti (0.5/1 μm), Cu (1/3 μm), and Ag (1.5/5 μm) layers, and the Crofer substrate was coated with Ag layers with a thickness of 1.5 and 5 μm, respectively.
