Abstract

Since plasma-spray ceramic coating is comparatively easy to form thick coating, this coating method is already applied as thermal barrier coating. When these structural materials modificated by ceramic coating were exposed at high- temperature environment, various problems such as corrosion, erosion and oxidation and so on. have been experienced. And in case when applying ceramics coating to actual components, it is very important to understand their degradation characteristics. Therefore, in this study, oxidation degradation characteristics of plasma-spray ceramic coating was evaluated under cyclic heating condition. And then, by means of observing their micro structure, the interrelation between the above result and their degradation characteristics was examined. And, for the purpose of improving oxidation-resis
