摘要：

The strain tolerance of thermal barrier coating (TBC) systems is limited by the properties of the ceramic coating. In this paper a bending test combined with acoustic emission measurements is described. The results show the ability of the method to investigate the degradation mechanisms of the ceramic TBC that result from mechanial loading. In addition, the possibility of conditioning the coating system by heat treatment is discussed.
