Mcral layer
摘要:
MCrAl layers according to prior art often display chipping of the thermally grown aluminum oxide layer (TGO) as a result of thermally induced stresses, which significantly reduces the oxidation behavior or the bonding behavior of ceramic heat insulating layers. An inventive MCrAl layer is designed in such a way that the TGO created thereon is microporous and thus allows expansion. The microporosity of the TGO is ensured by adding elements into the MCrAl layer in a targeted manner.
