Yttria-stabilized zirconia (YSZ) coatings were deposited at various arc currents of atmospheric plasma spraying. Two different technological configurations were used to form YSZ coatings; in first case, the plasma torch moved along the coated surface, while in another case, the coatings were formed on rotating substrate surface placed in front of the plasma torch. The thermal tests of the YSZ coatings were performed at temperature of 800 °C for 10 min. The surface morphology, elemental composition, phase structure and microhardness of YSZ coatings were investigated by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and Vickers indentation, respectively. It was obtained that the increase of the arc current from 180 A to 240 A enhanced the oxidation of the surface of the YSZ coatings. The XRD results indicated that the as-sprayed coatings consisted of the tetragonal ZrO₂ phase. The YSZ/substrate ratio increased steadily from 0.05 to 4.4 (before the thermal effect) with the increase of the current from 160 A to 240 A, when coatings were sprayed on the rotating substrates. However, neither the substrate position nor the thermal effect influences the phase structure of the YSZ coatings. The YSZ coatings sprayed on the rotating substrates were less porous, had lower amount of micro or macro cracks, demonstrated higher adhesion and better resistance to the thermal impact compared to the YSZ coatings deposited on the immobile substrates.

氧化钇稳定的氧化锆（YSZ）涂层是在大气等离子喷涂的各种电弧电流下沉​​积的。两种不同的技术配置被用来形成YSZ涂层。在第一种情况下，等离子炬沿涂层表面移动，而在另一种情况下，涂层形成在位于等离子炬前面的旋转基板表面上。YSZ涂层的热测试在800°C的温度下进行10分钟。通过扫描电子显微镜（SEM），能量色散X射线能谱（EDS），X射线衍射（XRD）和维氏压痕分别研究了YSZ涂层的表面形貌，元素组成，相结构和显微硬度。得到的是，电弧电流从180 A增加到240 A，增强了YSZ涂层表面的氧化。₂阶段。当在旋转的基板上喷涂涂料时，随着电流从160 A增加到240 A，YSZ /基板比率从0.05稳定地增加到4.4（在热效应之前）。但是，基材位置和热效应都不会影响YSZ涂层的相结构。与沉积在不动基体上的YSZ涂层相比，喷涂在旋转基体上的YSZ涂层的多孔性较小，微裂纹或宏观裂纹的数量更少，具有更高的附着力和更好的抗热冲击性。
