Structure‐thermal properties—relationship in plasma sprayed zirconia coatings

Plasma sprayed coatings of zirconia stabilized with 7, 8, and 20 wt.% of yttria were investigated. The microstructure of the coatings was characterized by optical microscopy and x‐ray diffraction. The thermal properties of the coatings, i.e., thermal diffusivity, thermal dilatation, specific heat, and resulting thermal conductivity were determined for each zirconia coating and the results were correlated with the microstructure.
