Abstract

The corrosion rate of AA(1) 7075 aluminum alloy in 0.1 M sodium chloride solution is decreased by the addition of 1000 ppm of FeCl2, cocl2, NiCl2, YCl3, LaCl3, NdCl3, PrCl3, or CeCl3. In each case, the protective cation is slowly incorporated into the oxide film which develops on the alloy surface d...
