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