Abstract Experiments showed that addition of various inhibitiors to Fe/0.05mol·L-1 HC1 system might result in various cathodic and anodic processes. Magnetic field, in general, did not influence the anodic dissolution processes of iron, but increased the anodic current density in film formation process. Magnetic field also did not influence the following cathodic processes: O2 diffusion, Sn2+ reduction, Sn2+ diffusion and H+ reduction on Sn-plated surface, but influenced H+ reduction on iron. In the presence of both inhibitor and magnetic field, a dynamic analysis of the interaction between the magnetic field effect and the inhibitor effect in the cathodic hydrogen evolution process was carried out, meanwhile, a dependence of the coefficient of magnetic field on the inhibitor coverage was derived.

Key words: Magnetic field Inhibitor Pe/HCl system Interaction Polarization behavior
