摘要: Abstract In order to study the applicability of SrY 2 O 4 thermal barrier coating (TBC) materials, expansion coefficient and conductivity were evaluated. A polycrystalline sintered was prepared by solid-state reactions SrCO 3 Y at 1273 K, followed spark plasma sintering 1773 K. The measured using a high temperature X-ray diffraction analysis. diffusivity laser flush method is 7.4 W m −1  K room temperature.
