Two glass compositions 40SiO 2 ·15B 2 O 3 ·27BaO·18MgO (mol.%) and 40SiO 2 ·15B 2 O 3 ·27BaO·10MgO·8ZnO (mol.%), with suitable properties for sealing applications in SOFC, have been tested under conditions simulating SOFC stacks. The test meth

This paper presents the influence of the cycling frequency on the Cr2O3 scale adherence during thermal cycling. Oxidation was performed on pure chromium in air between 800 and 1000 °C. It has been shown that material losses due to spallation are mor

The effect of small amounts of water vapour on the isothermal high-temperature oxidation behaviour of powder-metallurgical (PM) chromium in Ar/20% O 2 and N 2 /20% O 2 has been studied. Additional oxidation experiments were performed with isotopicall

Thin layer activation (TLA) has been applied to a study of the high-temperature cyclic oxidation behaviour of pure and yttrium-implanted chromium, taking advantage of the high area selectivity of the technique. On pure chromium, two different sample
