Abstract:

Accurate acquisition of thermomechanical parameters of thermal barrier coating in harsh environment is of great importance for the development of gas turbine and aero-engine. To meet these requirements, it is urgent to develop a new non-contact, non-destructive, transient response measurement technology. Thermomechanical parameter measurement technology based on phosphorescence is a new measurement method developed rapidly in recent years. It obtains the real-time thermomechanical information by measuring the phosphorescent signal. Combination of phosphorescence-based measurement technology and thermal barrier coating is a new technique, which could develop a novel thermal barrier coating with functions of thermal protection and thermomechanical parameter measurement. This article focuses on the newly developed thermal barrier coating with temperature and stress measurement function, the principle of phosphorescence measurement, phosphorescent materials, functional TBC fabrication, measurement methods and applications in temperature/stress measurement are described in detail. Finally, the future development of this technology is discussed.
