Aiming at the electromagnetic corrosion behavior of 2507 super duplex stainless steel used for ocean umbilical cable，the effects of electromagnetic field changes on the electrochemical properties of 2507 super duplex stainless steel in simulated seawater were studied by potentiodynamic polarization，electrochemical impedance spectroscopy and Mott Schottky analysis.Subsequently，SEM and EDS were used to analyze the corrosion morphology and products of 2507 super duplex stainless steel.Results showed that the electromagnetic field could promote the corrosion of 2507 super duplex stainless steel in 3.5%NaCl solution.As the intensity of the electromagnetic field increased，self-corrosion potential and the impedance decreased，so the corrosion became more serious.Meanwhile，the passivation film semiconductor formed by 2507 super duplex stainless steel in 3.5%NaCl solution generated P-N conversion，and the higher the excitation current，the more negative the conversion potential. |
