A life prediction algorithm has been developed, based on a damage accumulation algorithm that includes both cyclic and time-dependent damage. The cyclic damage is related to the calculated cyclic inelastic strain range in the ceramic coating; the time-dependent damage is related to the oxidation kinetics at the bond-ceramic by: Meier, Susan Manning, Nissley, David M., Sheffler, Keith D., and Cruse, Thomas A.

Thermal barrier coatings, used extensively on hot section gas turbine engine components, weaken and spall after repeated thermal exposure during normal engine operation.

A new technique has been developed, involving the use of vacuum impregnation of the porous ceramic with a mixture of epoxy and fluorescent dye (rhodamine-B) and the ASTM C –79 direct pull test, to preserve and reveal Cited by: The life prediction model was modified by the shear and normal strain range close to the interface of the top coat and TGO.

Based on the experiment data, the life prediction model of thermal fatigue of TBCs was set up for EB-PVD coatings. Finally, using the life prediction model, the life of TBCs was predicted under the designed load case. Scott, K.T. and Restall, J.E.

Initial cracks were introduced on the coatings’ top surface and cross section using the micro-indentation technique. The results show that crack length in the surface-cracked TBCs grew parabolically Author: Dowon Song, Taeseup Song, Ungyu Paik, Guanlin Lyu, Yeon Gil Jung, Baig Gyu Choi, In Soo Kim, Jing Zh.

In this work, a novel thermal barrier coating (TBC) system is proposed that embeds silicon particles in coating as a crack-healing agent. The healing agent is encapsulated to avoid unintended reactions and premature oxidation. Thermal durability of the developed TBCs is evaluated through cyclic thermal fatigue and jet engine thermal shock : Dowon Song, Taeseup Song, Ungyu Paik, Guanlin Lyu, Yeon Gil Jung, Baig Gyu Choi, In Soo Kim, Jing Zh.

Microwave-assisted thermal processing (MATP) and pressure-assisted thermal processing (PATP) technologies offer great potential to create high-quality, commercially sterile and pasteurized foods. However, for these technologies to reach their full commercial potential, they require high performance polymeric packaging that can withstand the thermal, pressure and electromagnetic stresses.

This work investigates the failure mechanism of an air plasma spraying (APS) thermal barrier coatings (TBCs) with various bond coat (BC) surface toughness under constant temperature loading condition.

Results show that the increased BC surface roughness decreased the lifetime. Moreover, the relationship between the TGO depth and the lifetime can be well described by linear law. Together with the R lines, the PS coefficients of peaks within the vibronic bands form the spectral parameters for our 3D stress measurement model.

This will provide a more exact stress-prediction method in non- destructive testing of the TGO and eventual life prediction of the thermal barrier coatings of aircraft engine turbine blades.
