abstract = {The oxidation resistance of the bond coat in thermal
barrier coating systems has significant influence on thermal
cycling performance of the protective coating. In this
study, the influence of varying the alumina content of
plasma-sprayed oxide dispersion strengthened bond coats with
CoNiCrAlY matrix material on the oxidation resistance was
analysed by thermogravimetric analysis, SEM and TEM. Yttrium
ions at the alumina scale grain boundaries and the grain
size in the scale appear as major factors influencing
oxidation properties. The ODS material with 2, 10 and 30
$wt\%$ alumina content was applied in TBC systems as an
additional thin bond coat. The thermal cycling performance
of those advanced TBC systems, in burner rig tests, was
evaluated with respect to the ODS material properties.
Thermal cycling behaviour is in good correlation with the
isothermal oxidation resistance. All results indicate that
TBC systems with 10 $wt\%$ alumina content in the ODS bond
coat have a superior thermal cycling performance, as
compared to ODS bond coats with lower or higher alumina
content.},
