Abstract
Graphite is one of materials used in metallurgical applications; however, it is characterized by low oxidation resistance. In the article, an yttrium oxide coating was deposited using Plasma Spray Physical Vapour deposition method (PS-PVD) on graphite. Next, the influence of selected process parameters (power current, powder feed rate, or plasma gasses composition) on coating thickness and structure were discussed. The obtained coatings were characterized by hybrid structure with partially formed columns. The linear relationship between power current and coating thickness was observed. There was no significant influence of other analyses' process parameters on coating thickness or microstructure. [ABSTRACT FROM AUTHOR]
