The service lives of the components in a gas turbine engine are usually limited by the components' damage tolerant life. However, for some turbine blades, hot corrosion and corrosion fatigue may make continued service untenable before the expiration of this life. The absence of industrialised non-destructive hot corrosion and corrosion fatigue detection techniques mean that some turbine blades are automatically removed from service at fixed intervals to mitigate the potentially-catastrophic impact of various corrosion mechanisms, even if substantial nominal damage tolerant life remains.This research will target understanding the corrosion mechanisms that may affect gas turbine engine components and the corresponding non-destructive detection techniques that may be used to improve the service life management of these components.

燃气涡轮机发动机中的部件的使用寿命通常受到部件的损伤容限寿命的限制。然而，对于某些涡轮机叶片，热腐蚀和腐蚀疲劳可能使其在寿命到期之前无法继续使用。工业化的非破坏性热腐蚀和腐蚀疲劳检测技术的缺乏意味着某些涡轮机叶片以固定间隔自动地从服务中移除，以减轻各种腐蚀机制的潜在灾难性影响，本研究的目标是了解可能影响燃气涡轮机发动机部件和相应非部件的腐蚀机理，破坏性检测技术，可用于改善这些组件的使用寿命管理。
