Degradation of ceramic coatings in demanding environments

陶瓷涂层已被开发用于保护工业应用中的衬底，如航空发动机和发电用工业燃气轮机，而陶瓷涂层在高温腐蚀环境等苛刻环境中的降解和失效机制非常复杂。在这个项目中，将使用各种表征工具来检查陶瓷涂层的微观结构演变、残余应力和机械性能。在此项目中产生的数据将用于了解陶瓷涂层在苛刻环境中的降解和失效机制。该项目的新颖之处在于开发陶瓷涂层的综合表征，结合先进的表征来研究陶瓷涂层在暴露于苛刻环境时的变化。能源是EPSRC的主要研究课题之一，本项目提出的涂层研究直接适用于发电、航空发动机等能源行业，与EPSRC的主题非常契合。

Ceramic coatings have been developed to protect underline substrates for industrial applications such as aero-engine and industrial gas turbine for power generation, while the degradation and failure mechanisms of ceramic coatings in demanding environments like corrosive environments at high temperature is very complex. In this project, various characterisation tools will be used to examine microstructural evolution, residual stresses and mechanical properties of the ceramic coatings. The data generated during this project will be used to understand the degradation and failure mechanisms of the ceramic coatings in the demanding environments. The novelty of the project is developing comprehensive characterization of the ceramic coatings using a combination of advanced characteisationl to examine how the ceramic coatings change during exposure to the demanding environments. . Energy is one of major research themes in EPSRC, the coating study proposed in this project is directly applicable to energy industry like power generation and aero-engine, so it aligns very well with the EPSRC theme.
