| Abstract: | The properties of 8wt%Y2O3-ZrO2(PSZ) powders for plasma-spraying prepared by coprecipitation were studied. Phase composition of powders was investigated by means of XRD. Morphology and state of agglomeration of the granular particles were observed by using SEM. The STEM was performed to determine grain size and chemical composition. Particle size distribution was measured by Laser-particle-size apparatus.Flowability of powders was tested by Powder-compies-characieristie apparatus. The relations between the properties and the fabrication technology were also investigated. Results showed that the powders had compositional homogeneity, large agglomeration size, ideal particles size distribution and high flowability. They can meet a plasma spraying criterion. |
