| Popis: | Al2O3 coatings obtained by the plasma spraying are applied for applications utilizing the electrical insulation properties of such electronics devise manufacturing equipment components. In recent years, it has been reported that Al2O3 coatings with excellent electrical properties can be obtained by suspension plasma spraying (SPS). From past studies, it is cleared that functional properties and characteristics of coating were strongly affected by SPS conditions. For example, ratio of metastable phase Al2O3 was much different by SPS conditions. On the other hand, functional properties were not correlated with coating properties on Al2O3 SPS coating. It is obvious that detailed understanding of phenomenon is necessary to advance Al2O3 coating technology. In this study, several SPS factors such as in-flight particle property, splat property and coating property were investigated in order to understand SPS phenomenon. |
