Influence des impuretés sur le comportement électrochimique d'électrodes dans la soude 0.1 N

Written by sctunisie no comments

The fact that mixed potential of aluminum in a 0.1 N NaOH solution at 60°C is more negative when the metal is purer can be readily explained by potential v s. time plots and volumetric measurements. these are consistent with impurities behaving as microcathodes which shift the mixed potential of pure aluminum towards higher potentials, the corrosion velocity being enhanced correlatively.
