Structure, Property and Processing Characterization of Plasma Sprayed Nanostructured Zirconia Coating

Abstract

Abstract: The nanostructured and conventional ZrO₂ coatings were deposited by atmospheric plasma spraying
technique (APS). The influence of the grain size and shape of feedstock and spraying parameters on the ZrO₂ coating was examined. The deposition
efficiency, roughness and Vikers microhardness of two kinds of ZrO₂ coatings were measured. The obtained results reveal that the nanostructured ZrO₂ coating possesses high and stable deposition
efficiency, more uniform microstructure, higher Vikers microhardness and lower roughness than that of conventional ZrO₂ coating.

Key words: plasma spraying, zirconia coating, spraying parameters, microstructure
