The thickness of oxide layer formed at bond coat/ceramic coat interface is regarded as a function of oxidation time and several parameters describing longitudinal and lateral oxygen transfer. The model is used to calculate the thickness of
在热障涂层的氧化模型研究中,不考虑陶瓷层,把在陶瓷层和粘结层之间生成的氧化物看作是由规则的氧化物晶粒组成。

Bond coat is a kind of coating that improved the interface conjunction between the bond coat and the top coat.
粘结层是在陶瓷层与金属基体之间的一层改善陶瓷层与基体粘结性的过渡层。
Impacted by creep and stress relaxation, the strain of bond coat layer increases irreversibly, and the TGO layer convolutes .
由于蠕变和应力松弛的影响，粘结层应变不可逆地增加，使TGO层的界面形貌出现起伏。
The results show that thermally grown oxide(TGO)was formed for the oxidation of bond coat during high temperature oxidization of APS TBC.
