The results show that the samples exposed to the air previously for 24 h can be passivated automatically in acetic acid solution with Cl- with the corrosion potential remaining 100mV.No such phenomenon was observed for samples which were cathodically polarized with the corrosion potential stabilizing at a value of -242±3mv. The passive film formed by anodically polarizing is more proof than formed in the air.
