چکیده مقاله:
Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size and lattice strain of YSZ calculated by the Williamson-Hall method. Morphology and particle size measurement observed by scanning electron microscope. Therefore, results showed the good spherical YSZ powders morphology and also phase transformations were in order to improve the properties of the fabricated powders. During the YSZ powders plasma process, some monoclinic phases transform to stable tetragonal phase.
