摘要：

On the basis of the literature data and the current results, a mechanism for thc pitting corrosion of Al alloys is proposed. An assumption is made that the transport of Cl- ions through detects in the passive film of aluminum and aluminum alloys is not a rate determining step in pitting. The pit development is controlled by the solubility of the oxidized alloying elements in acid solutions. A very good correlation was found between the pitting potential and the oxidized alloying elements for metastable Al-Cr, Al-Zr, Al-W and Al-Zn alloys.
