A Study of Thermal Fatigue Life Prediction of TBC

The research results presented here are the second part of the oxidation and thermal fatigue research of TBC (Thermal Barrier Coatings).Based on the previous experimental research,the life prediction model of thermal fatigue of TBC was formulated for two types of TBC:plasma sprayed and electrical beam physical vapor deposition coatings.Main work includes to set up the life prediction model of thermal fatigue of TBC,to develop a method for obtaining the parameters of the life model,and to give a method or procedure for obtaining stress/strain at the life critical location.The research has given a whole procedure for predicting the thermal fatigue life of TBC.And based on the results of thermal fatigue experiments,the procedure or method was evaluated and verified.
