摘要	The electrochemical behavior and oxide film structure of the weld of 316L/52M/A508 dissimilar metal welded joints were investigated via scanning electron microscopy (SEM), potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy (XPS). The electrochemical measurements revealed that the weld materials could be arranged in descending order of protectiveness of the oxide film formed on their surface; that is, Alloy52Mw>Alloy52Mb>C52M>C308. The results of EIS and XPS analyses showed that the oxide films formed on these materials were duplex-structured; this duplex structure consisted of a Cr-rich (in 52M nickel-based weld materials) or Cr/Fe-rich (in C308 stainless steel weld materials) inner layer and a Ni/Fe-rich (in 52M nickel-based weld materials) or Fe-rich (in 308 stainless steel weld materials) porous outer layer.
