According to the analytic formula for the diffusion flux. the results that the dispersive particles promote the formation of nodule-like Al2O3 oxides were explained by analysizing some influencing factors such as temperature of oxidation, size. Con tent and distribution of the dispersive particles. In the meantime. the mechanism that the dispersive particles promote the nucleation and re-formation of protective Al2O3 scale was proposed .Correspondent:(MA Xinqing, Institute of Corresion and Prolection of Metals.
