摘要	A sputtered coating of a low-Cr alloy without Si was deposited on the cast alloy with the same composition. The short term (100 h) oxidation behavior of the sputtered coating and the cast alloy was evaluated in air at 800 A degrees C. The results indicated that the sputtered coating exhibited a higher oxidation resistance than the cast alloy. It was found that the mass gain of the cast alloy increased continuously with oxidation time and was higher than that of the sputtered coating, which demonstrated only a slight increase in mass gain with oxidation time after 5 h thermal exposure. During the initial thermal exposure of 0.5 h, the oxide scale formed on the cast alloy consisted of Fe2O3 and (Fe,Co,Cr)(3)O-4 spinel with a small amount of Cr. However, (Fe,Co,Cr)(3)O-4 spinel and Fe2O3 were thermally grown on the sputtered coating. After oxidation for 100 h, the oxide scale formed on the cast alloy consisted of Co3O4 and (Fe,Co)(3)O-4 with internal oxide of Cr, while a double-layer oxide consisting of an outer (Fe,Co,Cr)(3)O-4 spinel layer and an inner Cr2O3 layer was developed on the sputtered coating.
