SEM image and results from cross-sectional EDS analysis of M-C spinel-coated surface-blasted AISI 441 after oxidation at 800 °C for 20,000 hours (element concentrations in atomic percent). Note excellent scale adhesion and limited transport of Cr into the coating (right side of image).
Post-test image of SCN-1 compliant glass sealed between aluminized AISI441 and an anode/electrolyte bilayer. No evidence of damage or leakage was observed after 12 thermal cycles between RT and 800 °C.
Progression of damage and healing of a viscous glass sealant during thermal-mechanical loading of an SOFC stack.
Response surface prediction and associated error for use in reduced order models (ROMs) of SOFC stack performance.
Stack test fixture used for evaluation/validation of new cell and stack materials under realistic stack environment conditions.
Use of pyramidal micro-indentation tests to characterize interfacial toughness for the interconnect scale.
