电子束物理气相沉积热障涂层技术是一项用于保护航空发动机热端部件的关键技术。热障涂层除了要完成降低热端部件工作温度（或提高发动机工作温度）的任务之外，另一项主要任务就是防止高温腐蚀。本文通过理论分析和实验证实，在以ＺｒＯ２为基的隔热层中，由于粘结层氧化所需氧量极少，其氧气分压与环境中的氧分压几乎一样，因此热障涂层系统中粘结层的高温氧化与陶瓷层厚度基本无关。同时还系统地分析了粘结层合金的选择、不同合金元素的作用及其对抗高温氧化性能的影响。
Electron Beam Physical vapor deposition (TBC) thermal barrier coating technology is a key technology used to protect the hot-end components of aero-engines. Thermal Barrier Coatings In addition to the task of reducing the operating temperature of hot end components (or increasing the operating temperature of the engine), another major task is to prevent high temperature corrosion. This paper through theoretical analysis and experiments confirmed that in the ZrO2-based insulation layer, due to oxidation of the bond layer requires very little oxygen, the partial pressure of oxygen and oxygen partial pressure in the environment almost the same, so the thermal barrier coating The high temperature oxidation of the adhesive layer in the system has little to do with the ceramic layer thickness. At the same time, we also systematically analyzed the choice of bonding layer alloy, the effect of different alloying elements and its effect on high temperature oxidation resistance.
