It showed a good combination between interface and substrate, and the coating zone showed a large number of defects, such as cracks and voids. Fig. 1b, the interface between coating and substrate appeared intermittent separation (The white arrows), spectrum analysis found that near the surface of the separation zone is mainly oxide. |

It was showed that there had been a good integration between the interface and substrate and a large number of defects such as cracks and cavities in the coating zone. In Fig. 1b, there had also been intermittent separation along the interface which was between the coating zone and substrate (demonstrated by the white arrows). It was found that the main composition near the crack surface was mainly composed of oxides with the EDS spectrum analysis.
