为了进一步提高封严涂层与基体材料之间的附着性能， 对梯度封严涂层与1Cr18Ni9Ti不锈钢之间的附着性能进行了探讨。采用拉开法测试梯度封严涂层与1Cr18Ni9Ti不锈钢之间的附着强度，并用冷热循环法测试梯度封严涂层的耐冷热循环性能，与普通封严涂层的附着强度及耐冷热循环性能进行比较，结果发现：梯度封严涂层的附着强度比普通封严涂层的附着强度有提高，而且梯度封严涂层的耐冷热循环性能明显优于普通封严涂层。
In order to improve the adherence of the abradable seal coatings farther,the gradient abradable seal coating was investigated .Adherence of the gradient abradable seal coating on 1Cr18Ni9Ti stainless steel substrate and cool-hot cyclic test resistance of it were examined.The results show that，compared to usual abradable seal coating ,the adherence of the gradient abradable seal coating is better，and the cool-hot cyclic test resistance of the gradient abradable seal coating is greatly improved. The gradient abradable seal coating spalls from 1Cr18Ni9Ti stainless steel substrate at least after 58 cool-hot cycles，and usual abradable seal coating spalls from 1Cr18Ni9Ti stainless steel substrate after 38 cool-hot cycles.
