3404 Thermal Cycle Damage Behavior in the Air Plasma Sprayed Thermal Barrier Coatings
Details
The thermal cycle tests of the air plasma sprayed thermal barrier coatings were carried out by means of the electric furnace or the high frequency induction heating system. In this study, the in-situ damage behavior was measured by using the acoustic emission system. The experimental results indicated that the thermal cycle damage occurred in cooling stage mainly. The effects of the heating method and the thermal cycle wave on the damage behavior were discussed.
