Influence of Service Temperature on Grain Growth and Thermal Diffusivity of Nanostructured Thermal Barrier Coating
The as-sprayed zirconia coating had an average grain size of 67 nm. Thermal treatment results showed that the grains of the nanostructured coating grew slightly below 900°C, whereas over 1000°C the gains grew rapidly. The thermal diffusivity of the coating increases with increasing heat-treatment temperatures.
