Influence of the densification process on the structure of Nano-Zirconia Particle in Plasma Spraying

  In this paper, Nanostructured yttria stabilized zirconia (YSZ) partides in plasma spra ying were collected by the pure water and the influ ence of densification process on the structure of Nano-YSZ Particle in plasma spraying were stud ied.The results showed that, trend of shrinkage of nano-zirconia reunion powder were appeared sig nificantly because of nano-zirconia particle grew up and melted.The residence time and degree of heat subjected of the powder in plasma flame flow zone was different, it was affected by the role of melt-quenched and gas expansion, the appear ance of powder experienced the different stages of morphology including the type of microcrack, melt acicular the stomata and dense spherical shell .The morphology inside of the powder experi enced the different stages of morphology including micro cracks pore, uniform spherical pores , and hollow structure.The evolution process can provide the necessary data referencefor for the appli cation of mmo-YSZ coating and improvements for the performance.
