Joining of Co coated ferritic stainless steel to ceramic solid oxide cells by a novel Ag-SiO2 braze
文献摘要：
A novel Ag-SiO2 braze for Solid Oxide Cells was successfully developed and applied to join Co coated AISI 441 ferritic stainless steel to YSZ-NiO half cells.The braze showed an improved wettability on the coated steel and the YSZ compared to pure Ag.A defect-free steel/YSZ joint was obtained using an Ag-1SiO2 braze jointed at 1000℃for 30 min in air.The microstructure of the joints was characterized by scanning electron microscopy and transmission electron microscopy with energy-dispersive X-ray spec-troscopy.Furthermore,a Co-Si-O2 phase diagram was calculated and used to explain the experimental results and formulate a reaction mechanism.It was found,that during the air brazing process,Co3O4 and(Co,Fe)3O4 are formed by the oxidation of the prefabricated Co coating.The growth of Cr2O3 was effec-tively impeded by the formed Co-based spinels.In a second step,Co3O4 reacts with the SiO2 present in braze.The Co2SiO4 formed by the reaction ensures a firm bonding between the steel and Ag-SiO2 braze.
