Abstract AITranslate

To improve the corrosion resistance of low-carbon microalloyed steel in marine environments,the corrosion behavior of the test steel with different cerium(Ce)contents in a marine environment simulated with 3.5%NaCl solution was studied by employing metallographic microscope,SEM,EBSD,and electrochemical analysis.The results show that the microstructure of the test steel mainly consists of ferrite and pearlite.Ce can refine the grains,reduce the size of inclusions,and modify the Al2O3,MnS,and Al2O3+MnS inclusions in the test steel into MnS+CeAlO3 and Ce2O3.The modified inclusions significantly reduce the stress,thereby decreasing the probability of micropore and crack initiation.Additionally,the addition of Ce can decrease the corrosion current density of the test steel,increase the corrosion potential,reduce the content ofγ-FeOOH in the corrosion products,and increase the content ofα-FeOOH and Fe3O4,lowering the reaction activity and enhancing the protective effect of the rust layer on the substrate.Therefore,compared with low-carbon microalloyed steel without Ce addition,the low-carbon microalloyed steel with Ce addition exhibits better seawater corrosion resistance.
