The displacement of the thermally grown oxide in thermal barrier systems upon temperature cycling
Models that characterize the displacement instability of the thermally grown oxide (TGO) found in some thermal barrier systems are reviewed, consolidated and extended. It is demonstrated that the simulations are only consistent with the observations whenever the bond coat and TGO both undergo plastic deformation. The TGO yields at the peak temperature, during growth, while the bond coat yields ...
متن کاملMathematical Analysis of Microstructural Characterizations for Thermally Grown Oxide Layers in Thermal Barrier Coatings
The thermomechanical properties of thermal barrier coatings (TBCs) such as elastic modulus, thermal conductivity, and coefficient of thermal expansions are determined by pores, cracks, and splat boundaries, which affect the thermoelastic properties of thermally grown oxide (TGO) layer and the fracture behavior in TBCs. The thermoelastic characteristics thus have been investigated through mathem...
متن کاملSynthesis of advanced aluminide intermetallic coatings by low-energy Al-ion radiation
Metals that work at high temperatures (for instance, superalloys in gas-turbines) depend on thermally grown oxide (TGO, commonly alumina) to withstand corrosion attack. Nickel Aluminide (NiAl) as one superior alumina TGO former plays an important role in protective coatings for turbine blades in gas-turbine engines used for aircraft propulsion and power generation. Lowering TGO growth rate is e...
متن کاملCrack propagation in thermal barrier coating systems
Thermal barrier coating systems are used on top of highly stressed components in gas turbines to protect the nickel-based substrates. A well-established thermal barrier coating system consist of the bond-coat (BC) and the thermal barrier coating (TBC). A third layer is grown during service: the thermally grown oxide (TGO) between the BC and the TBC. The coatings fail in service because of diffe...
متن کاملThermal Conductivity of a Zirconia Thermal Barrier Coating
The conductivity of a thermal-barrier coating composed of atmospheric plasma sprayed 8 mass percent yttria partially stabilized zirconia has been measured. This coating was sprayed on a substrate of 410 stainless steel. An absolute, steady-state measurement method was used to measure thermal conductivity from 400 to 800 K. The thermal conductivity of the coating is 0.62 W/(m⋅K). This measuremen...
