| Abstract: | The graph of the aluminium corrosive electrical potential pH was gained by the measurement of different aluminum corrosive potential in the different pH water dissolution. The best passivation point of pH was determined by analyzing the reaction in every phrase boundary line in the graph. The polarization curves of aluminum in the pure water and the man made sea water are presented. It is shown the best passivation point of pH is 5 7 and aluminium is more corrodible when haloid ions exist. |

| Keywords: | the corrosive electrical potential pH the polarization curve |
