Abstract: The polarization resistance (Rp) has been used to monitor the corrosion of aluminium in aqueous solutions in the pH range 1-13 and in the presence of 1M NaCl. The effects of time, nitrogen, temperature and some dithiocarbamates have been studied. The Rp-pH curves in air and nitrogen saturated solutions are bell shaped showing its lowest value at pH 13. In solutions without inhibitors, the Rp has been found to change with temperature according to the relationship Rp =a-bt, while in the presence of inhibitors the relationship is more complicated. The effect of inhibitor concentration is found to depend on the type of inhibitor and pH. The kinetic parameters have been evaluated for uninhibited and inhibited reactions.
