چکیده
The present work investigates the low-cost steels AISI 441, 430, and 444 against tailor-made high Cr steel Crofer 22 APU (22.9 wt% Cr) at 800 °C in simulated solid oxide fuel cell (SOFC) cathode conditions. Furthermore, a low steel, 409 (11.4 is included study. oxidation, chromium evaporation, area-specific resistance (ASR) of uncoated Ce/Co-coated are studied for up to 3000 h. showed significant improvement behaviour compared their counterparts. oxidation evaporation between varied substantially while Ce/Co coated exhibited highly similar behaviour. was on par with APU. However, 430 formed continuous silica layer, resulting higher ASR after Cross-sections were analysed using scanning electron microscope energy dispersive X-ray spectroscopy.

In the present study, electrophoretic deposition (EPD) method in different electric fields (30 – 300 V / cm) was used to apply Co3O4 spinel coating to SUS 430 as SOFC interconnect. The coated and uncoated specimens were pre-sintered in air at 800 and 900 °C for 3 h followed by cyclic oxidation at 700 and 800 °C for 500 h, respectively.

In the present study, Mn - Cr spinel powder was synthesized through a solid state reaction. In the next step, the electrophoretic deposition (EPD) method was used to apply the MnCr2O4 spinel, as an oxidation-resistant layer, on SUS 430 stainless steel in a potential of 300 V/cm. The coated and uncoated samples were then pre-sintered in air at 900 °C for 3 h followed by cyclic oxidation at 800 °...
متن کاملDevelopment of Copper-Ferrite Spinel Coating on AISI 430 Steel Used as Solid Oxide Fuel Cell
The bare and pre-oxidized AISI 430 pieces were screen printed by copper ferrite spinel coatings. Good bonding between the coating and the substrate was achieved by the reactive sintering process of the reduced coating. The energy dispersive X-ray spectroscopy (EDS) analysis revealed that the scale is a double layer consisting of a chromia-rich subscale and an outer Cu/Fe-rich spinel. The result...
