The　effect　of　temperature　on　the　oxidation　resistance　of　a　novel　wear-resistant　Fe-10Cr-1.5B-6Al-0.3C-0.8Mn-0.6Si　alloy　is　investigated.　The　mass　growth　rate　shows　that　this　alloy　exhibits　superior　oxidation　resistance　at　900　degrees　C.　As　the　oxidation　temperature　increases　from　900　degrees　C　to　1100　degrees　C,　the　structure　of　the　observed　oxide　scales　transforms　from　a　porous　bilayer　to　a　flat　monolayer,　while　the　oxidation　rate　increases　sharply.　The　selective　oxidation　of　Al　suppresses　the　outward　diffusion　of　Cr　and　Mn　to　form　MnCr2O4　oxides　in　the　monolayer　oxide　scale,　thereby　decreasing　the　oxidation　resistance　at　1100　degrees　C.
