| Research Abstract |
Resonance ultrasound spectroscopy by needle-transducer tripod was developed into high temperature measurement, up to 1073K, in order to clarify the all directional elastic moduli. The technique was applied to heat resistant coating, CoNiCrAlY, and thermal barrier coating, zirconia. The elastic moduli in the directions of out-plane and in-plane of the coatings were evaluated. It was found that the anisotropy of elasticity was able to be controlled by spraying powder size and thermal treatment.
