Abstract

An industrial thermal-barrier coating designated PWA 266, processed by electron-beam physical-vapor deposition, was measured using a steady-state thermal conductivity technique. The thermal conductivity of the 7%, by mass, yttria-stabilized zirconia coating was measured from 100 C to 900 C. Measurements on three thicknesses of coatings, 2mm, 3 mm, and 7 mm resulted in thermal conductivity in the range from 1.5 to 1.7 W/(m K), given the uncertainty of the measurement. The thermal conductivity is essentially independent of temperature.
