| Abstract: | The interface characteristics of substrate-metal bond coat layer and the layer-ceramic coating were studied by transmission electron microscopy (TEM) in the plasma sprayed duplex coating system consisting of a Al 2O 3+13wt%TiO 2 ceramic layer and a NiCrAl bond coat layer. It was found that the microstructure of the two interfaces is similar. Moreover, the two interface regions, which are of a certain thikness but non-uniform, are composed of a few phases, such as , amorphous, micro-crystalline, nanocrystalline phases. |
