abstract = {A gas-tight cobalt-based protective coating was
successfully applied by electroplating and subsequent
oxidation. The coating covered all the surfaces of the
machined gas channels of the metallic interconnect and
adhered well to this substrate. Such a gas-tight coating
offers effective blocking of Cr diffusion or evaporation
from the interconnect and hence a reliable protection
against Cr poisoning of the SOFC cathode. Chemical
interactions were observed between the cobalt coating and
the LSM contact layer, resulting in layer spallation during
oxidation under pressureless conditions. Applying a pressure
to the layers, spallation was effectively prevented.
Although the area specific resistance (ASR) of the coated
interconnect was higher than the uncoated one, it decreased
steadily with time within the measurement period. The ASR
was 28 m Omega cm(2) after an exposure of 1170 h. It seems
thus that electroplating followed by oxidation is a
promising method for the fabrication of spinel protective
coatings for SOFC interconnects or other balance-of-plant
components with complicated gas flow paths. (C) 2010
