Degradation of TBC Coating during Low-Cycle Fatigue Tests at High Temperature
Original language description
The work is focused on the study of degradation of ZrO2 stabilized by Y2O3 (YSZ) thermal-barrier-coating system with CoNiCrAlY bond coat applied on cast polycrystalline nickel-based superalloy Inconel 713LC. Cylindrical specimens in as-coated conditionswere cyclically strained under strain control with constant total strain amplitude in symmetrical cycle at high temperature (900 °C) in air. The coating thickness and hardness profile was measured. Fracture surface, surface relief and polished sections parallel to the specimen axis were examined to study damage mechanisms in coatings under cyclic loading at high temperature. It was find that initiation of the fatigue crack usually occurs on interface YSZ-CoNiCrAlY and the trajectory of the further crackpropagation was documented.
