| Özet |
| Plasma-sprayed ceramic coatings are widely used for structural applications in order to improve resistances to wear, friction, corrosion and oxidization [1]. In atmospheric plasma spraying (APS) one of many plasma spray methods, a coated layer is formed on a substrate surface by spraying melted powders onto a substrate at a high speed using a high-temperature plasma jet [2, 3]. Powder grains are transported within a carrier gas at hightemperature and high speed, injected into plasma jet. The melting powder is transferred to the substrate surface being coated and after impact, lamellar layer formation occurs [4]. Optimization of spray parameters is important for obtaining high-quality coating. In conventional plasma spray coatings, Argon (Ar) is used as the carrying gas. However, oxygen is also used as carrier gas in hightemperature plasma jet for the metal oxide powders to minimize decomposition of the metal oxide powder and the plasma coated material, as it improves the heat transfer characteristics of plasma during the spraying process [5]. Insufficient melting can occur if powder particles are too large. Optimum grain size and distribution affect the melting point of the material, the spray system used and application method of the coating [6]. In previous studies, it was determined that the microstructure of the coating material depending not only on the characteristics of the thermal spray powder but also on the hot spraying conditions [7-9].Al2O3, Al2O3+ TiO2, NiAl, NiCrAl and ZrO2 ceramic coatings produced by plasma spraying are well known against wear and maintain resistance to corrosion under certain conditions [10-13].
