| Abstract: | Objective To develop experimental simulation system for the erosion service environment of thermal barrier coatings, so as to study the erosion failure mechanism. Methods An oxy-fuel burner was developed to simulate high-temperature erosion of TBCs, and a particle feeding system with controllable speed and flow of particles was designed in the burner. Meanwhile, an acoustic emission system capable of real-time monitoring crack evolution was integrated in the device. Results This system realized the simulation of the erosion service environment of thermal barrier coatings, the simultaneous collection, output and display of temperature field, crack evolution damage parameters, and accomplished the integrated design of erosion service environment simulation and real-time monitoring of critical damage parameters. Conclusion This device can successfully simulate different experimental conditions such as room or high temperature, various impact angles and various particle velocities. Besides, this device can provide systematic damage parameters monitoring data for the understanding of erosion failure and the preparation optimization of TBCs. |
