| Abstract: | The structure of surface original scale of 510L hot rolled strip was processed by heat treatment at different temperatures.Corrosion behavior of hot rolled strips with different oxide scales structure was investigated in sodium bisulfite solution by SEM,XRD,EDS,polarization curves and electrochemical impedance spectroscopy(EIS).The results show that when temperature is below 570℃,the microstructure of oxide scale evolved into coniferous shape from granular with burr,the oxide scales become more dense and the relative content of Fe2O3 increases with temperature increasing.White diffusion-like phases on the oxide scales reduce with temperature adding,while the thickness of oxide scales increases.The order of corrosion resistance of the scales prepared at different temperatures from good to poor is as follows: 550,500,450,400,350℃.When 570℃>T> 450℃,the corrosion resistance of original scale can be improved by heat treatment. |
