BRAZING OF STAINLESS STEEL TO YSZ USING SILVER-BASE BRAZES

摘要

Three silver braze alloys (PalCuSil-10, PalCuSil-15, and TiCuSil) were evaluated for oxidation behavior, and their effectiveness in joining YSZ to steel. TGA, SEM and EDS were used to evaluate the braze oxidation behavior, and structure and chemistry of the joint. Chemical interdiffusion led to compositional changes, and yielded metallurgically sound joints. The effect of the braze and joining process on the interfacial microstructure and composition is discussed.
