Development 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...
متن کاملElectrophoretic deposition of MnCr2O4 coating for solid oxide fuel cell metallic interconnects
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 کاملThermal Growth Cu1.2Mn1.8O4 Spinel Coatings on Metal Interconnects for Solid Oxide Fuel Cell Applications
A novel cobalt-free Cu1.2Mn1.8O4 spinel coating is prepared and evaluated for the metal interconnect of solid oxide fuel cell. Mn-35Cu and Co-35Mn alloy coatings are deposited on 430 SS substrate and then in-situ oxidized in air at 750 ◦C for 100 h. XRD results confirm that Cu1.2Mn1.8O4 spinel with some Mn2O3 is formed, and the average thickness of the coating is 70–80 μm according to cross sec...
متن کاملCatalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application.
Catalyst layers (4-20 microm) of rhodium (1 wt%) supported on alumina, titania, and ceria-zirconia (Ce(0.5)Zr(0.5)O(2)) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water. Catalytic performances were studied for low-temperature (< or = 500 degrees C) steam reforming of propane at a steam to carbon ratio equal to 3 and l...
