通过对热障涂层厚度与其表面粗糙度关系的研究，初步探讨了涂层表面粗糙度对其高温氧化性能、隔热性能和热循环性能的影响，研究表明涂层的表面粗糙度随着热障涂层厚度的增加而增大，并且随着涂层粗糙度的增加，涂层的热循环寿命先增加后减小，而其在高温氧化过程的初期，涂层重量增加迅速，氧化20h后重量增加减缓。

The relationship between thickness and roughness of thermal barrier coatings surface is studied. The effect of surface roughness on high-temperature oxidation resistance, thermal insulation properties and thermal cycling performance is discussed. It is found that with thickness increasing surface roughness increases, and thermal cycle life first increases and then decreases. Result of High-temperature oxidation properties show that the weight of coatings increases fast in the beginning and the increasing slowing down after 20 hours.
