高温涂层材料物理、力学性能研究进展

Progress in Mechanical and Physical Properties of High-Temperature Coating Materials

高温涂层的广泛使用在很大程度上拓展了高温合金的应用领域,但随着航空发动机用涡轮叶片服役环境的日益苛刻,合理评价涂层/高温合金体系综合性能,尤其热机械疲劳、蠕变疲劳等性能备受关注。该体系综合性能的评价必然涉及到与高温涂层材料本身相关的物理、化学、力学等性能。本文将对近年来有关高温涂层材料的物理和力学等方面的性能进行综述,并据此探讨今后涂层/基体界面行为研究的新思路。

The important applications of high-temperature coatings significantly extend the scopes of superalloys. For the gas turbines at the severe working environment, much attention can be paid on the reasonable estimation of the integrated coating-superalloy system, in particular, thermal mechanical fatigue and creep fatigue. It is evidently revolved into the related physical, chemical and mechanical performances of the high-temperature coating materials. In this paper, the physical and mechanical properties of high-temperature coating materials were reviewed and the interface behavior between coating and superalloys was also explored in the near future.
