采用空气等离子喷涂方法制备了Ni-22 Cr-10Al-1 Y/ZrO 2 - 8 Y2 O3和Ni-22 Cr-10Al-1 Y/ZrO 2 - 25 CeO 2 - 2. 5 Y2 O3金属/陶瓷涂层，并在900、1000和1100 °C下进行了氧化。氧化产物主要为α-Al_2O_3，它是由向内渗透的氧离子在金属/陶瓷相界与Al反应生成的。此外，Ni和Cr的氧化也在一定程度上发生。
Metal/ceramic coatings of Ni–22Cr–10Al–1Y/ZrO2–8Y2O3and Ni–22Cr–10Al–1Y/ZrO2–25CeO2–2.5Y2O3, which were prepared by the air plasma spray method, were oxidized at 900, 1000, and 1100 °C in air. The major oxidation product was α-Al2O3, which was formed by the reaction of inwardly penetrating oxygen ions with Al at the metal/ceramic phase boundaries. The oxidation of Ni and, moreover, Cr also occurred to a certain extent.
