Abstract：Aero-engine combustion liners are subject to tough service environments, such as high temperature, high pressure, high thermal stress and vibration stress. As aero-engine performance is enhanced, combustion temperature is increased continuously, and thus it raises higher requirements on cooling structure, substrate material, and surface protection. Focused on foreign aero-engine combustion liner, this paper introduces structural design characteristics for top three manufacturers, and reviews applications of material and manufacture process. It reveals commonly used superalloys along with its properties, and processes of casting, sheet metal working, welding, coating, laser drilling. Finally, it describes prospects of combustion liner material and manufacture process, as well as latest progress and application of ceramic matrix composites.
