Summary

Cyclic burner rig test was performed with model parts of gas turbine nozzle made of silicon nitride with and without environmental barrier coating (EBC) based on lutetium silicate. A short cycle of burner rig test were repeated up to 100 minutes of holding time at 1400 °C, followed by 10 cycles of 1 minute holding each at every 50 °C increase of holding temperature up to 1600°C. the model part showed no visible cracks under zyglo inspection after the test cycles. the model part without EBC showed a little weight increase after the test cycles, whereas the part with EBC showed a slight weight decrease. the thermal stress distribution analysis was carried out by FEM based on the temperature distribution recorded by ThermoVison infrared camera during the test cycles. the maximum stress after flame turned off was 175 MPa which is lower than the strength of the material (400 MPa at 1500 °C), suggesting the validity of the application of the material to real parts.
