AbstractNanostructured thermal barrier coating was prepared by air plasma spraying with the YSZ (8%Y2O3-ZrO2, mass fraction)nanopowder with particle size range of 30-50 nm and grain size of about 12 nm. The microstructure of the nanocoatings was analyzed. The results show that the average grain size of the coating is about 20-30 nm, while exit some abnormal coarse grains of about 200-300 nm. The coating composes of c-ZrO2 and t'-ZrO2 phase. The domain structure is. found in the t' phase. Pores in the coating are small, disperse and in closed shape., Lath-shape structure and dislocation tangles appear as well.
