Abstract In order to study the compound effect of chromium and heating process parameters (heating temperature,holding time) on the oxide scale formed on the surface of hot rolled low carbon steel,the effect of chromium content on high temperature oxidation behavior of low carbon steel in air at 1 100-1 250 ℃ was studied by thermogravimetry analysis. The oxidation rate constant was calculated. The phase composition,the micro-structure and the element proportion of oxide scale under different experimental conditions were compared. The results show that the high temperature oxidation presented a two-stage model. The oxidation kinetics curve was linear in the early stage of oxidation,and then changed to parabolic in the middle and late stage of oxidation. The transformation time from linear to parabolic was shortened with the increase of chromium content in the steel. The structure of the oxide scale was composed of the outermost Fe₂O₃ layer,the middle Fe₃O₄ layer and FeO layer,and the chromium rich spinel (FeCr₂O₄) layer near the substrate after the adding of the chromium. In the oxidation process,the FeCr₂O₄ layer suppressed the outward diffusion of the iron ions and the electrons,and reduced the oxidation rate. Meanwhile,the high temperature oxidation resistance of low carbon steel was significantly improved.

Key words： low carbon steel chromium oxidation kinetics oxide scale rich-chromium spinel
