The Y2O3-CeO2-ZrO2 powders were prepared using a co-precipitation process and the corresponding coatings were prepared by plasma spraying.The results show that an optimal composition exists in Y2O3-doped CeO2-ZrO2,but not in CeO2-doped Y2O3-ZrO2.The powders mainly contain tetragonal phase and a trace amount of monoclinic phase.The homogeneity in composition,large agglomerate size,ideal particle size distribution and high flowability were obtained.The as-sprayed coatings are composed of non-transformable tetragonal phase,tz′structure,and resistant to transformation under thermal or mechanical stresses.
