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 oxide layer.

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。

When Al_2O_3 composite ceramic was plasma sprayed directly on the substrate, the substrate was burned out. So a bond coat should be produced on the substrate firstly.

用等离子喷涂方法在基体上直接制备陶瓷层时,基体被烧坏,因此,应首先喷涂一层打底层。
