Effect of Rare Earth on the Inclusions and Pitting Resistance of duplex Stainless Steel

摘要：

　　The anodic polarization curves of 2205 duplex stainless steel with various RE contents in 3.5% NaCl neutral solutions have been measured by electrochemical methods,The effect of rare earth on pitting corrosion resistance of 2205 duplex stainless steel has been studied by the metallographic examination.The results show that RE can effectively depress pitting corrosion,while the irregular inclusions of Al2O3,sulfide in the shape of clump are transformed into tiny dispersive round or oval RE inclusions,and it plays a good role in pitting resistance.
