| Abstract: | The electrochemical states and cathodic polarization behavior of Fe/xH2SO4 y/K2Cr2O7 systems (x=0.1- 2 mol/L, y/=0.01-0.4 mol/L) were investigated. The electrochemical states of iron in relation to H2SO4], K2Cr2O7] and H2SO4]/K2Cr2O7] ratio were established, including active state, passive state and metastable state. Five types of cathodic polarization curve were analysed and the effect of magnetic field (0.4T) on the cathodic process was discussed. |
