Vertical and in-situ growth of hexaaluminate embedded in alumina intermediate layer with high stability†
Abstract
Hexaaluminate (HA) has been in-situ prepared by sharing the aluminum ions from Al2O3 intermediate layer (IML) supported on the FeCrAl alloy foil. The results show that the HA is vertically embedded in Al2O3 IML, and compared with Al2O3 IML, the obtained HA-Al2O3 composite IML shows better adhesion stability.
