Highly oxidation resistant component

摘要

Highly oxidation resistant components as known in state of the art disclose a MCrAlY layer, which shows a poor anchoring between the thermal barrier coating and the oxide layer on the MCrAlY layer. The heat resistant component (1) discloses a MCrAlY layer (16), which has an outer layer (19) of the composition of ²-NiAl, so that a meta-stabile aluminium oxide is formed, which leads to a good anchoring of the thermal barrier coating (13) to the thermally grown oxide layer.
