| Research Abstract |
The elastic moduli of thermal barrier coatings are necessary to calculate the parameters of material mechanics, such as thermal stress, interfacial fracture toughness and so on. The resonance ultrasound spectroscopy system for all the anisotropic elastic moduli at high temperatures up to 1100℃ was successfully developed. All the anisotropic elastic moduli dependent on environmental temperature were measured. The thermal barrier coating showed strong anisotropic elasticity. The Young's moduli and shear moduli increased because of high temperature sintering.
