| Abstract: | At present,thermal barrier coatings （TBCs） as one of the most advanced high temperure protection coatings have been wildly used in gas turbine engine blades. In this paper, high temperature environment simulation system has been used for studying YSZ TBCs heat insulation property after thermal endurance test under simulative engine environment. Also, obtained change rule of YSZ TBCs heat insulation property after long time working under laboratory environment and analyzed relationship between microstructure and heat insulation property. |
