摘要	The effect of element Cr on Filming behaviours of Fe-xCr-10Al (all in at.%) alloys during initial stage oxidation was studied by oxidizing Fe-10Al, Fe-5Cr-10Al, and Fe-10Cr-10Al in 0.1 MPa oxygen at 1173 K and 1273 K, respectively. The morphologies and compositions of the transient oxide films formed on these alloys were investigated using SEM and AES. The AES analyses indicated that the alloy elements were oxidized to form respective oxide at the onset of the oxidation, but the effect of the third element Cr in Fe-xCr-10Al on promoting Al(2)O(3)-rich film formation was determined by the element contents and oxidation temperature. The establishment of Al(2)O(3)-rich film on Fe-10Cr-10Al was more rapid than on Fe-5Cr-10Al, and higher temperature promoted the selective oxidation of Al.
