采用动电位扫描极化曲线、恒电位极化和电化学阻抗谱研究了磁场对铁在含亚硝酸钠的氯化钠溶液中电化学行为的影响.结果表明:外加0.4T磁场使得自腐蚀电位下电化学阻抗谱中容抗弧半径变小;外加磁场导致阳极极化曲线在初期出现阴极电流,并在钝化区内降低外测电流密度;外加磁场增加高电位极化下的阳极电流密度.
The effects of a magnetic field on the electrochemical behavior of iron in a sodium chloride solutions with nitrite were studied by potentiodynamic polarization curve,potentiostatic polarization and electrochemical impedance spectroscopy.A 0.4T magnetic field decreased the electrochemical impedance capacitive arc radius at the open circuit potential.A cathodic current was observed at the beginning of anodic polarization curves.The measured current density values in the passive region were decreased after imposing a magnetic field.The applied field increased the anodic current density at high potentials.
