Abstract

Corrosion mass loss and polarization curve of aluminum in 1 mol dm-3 aluminum chloride solution were measured. The polarization resistance-current density plotting, which is differentiated from the experimented polarization curve, was simulated and considered as a parallel electric circuit of both anodic and cathodic polarization resistances. Current density(0.013~0.017 mA・cm-2)obtained by differential polarization method has roughly agreed with value of 0.012 mA・cm-2 of corrosion current density calculated from corrosion mass loss of the aluminum specimen in the aluminum chloride solution.
